Hello I've finally got Spot to auto start and a bunch of other problems fixed but when I try to play a song it gives me this error

"playing spotify:album:6Bp2ojsBc8CtNaYipdxCLt spotify:track:3ZcLmonVVD1MTQtmQb8yf3 error! no devices"

I saw in the Github issue #4 someone had this error but they fixed it so I applied the fix to mine and it didn't do anything. Got a solution or an idea?

Hi everyone,

I noticed a very high CPU usage if I run just click even without the UI. Did anyone else notice this and did anyone find a better solution?

So far I have tried to rewrite the click.c code into a python class which could be used by the frontend directly, which was much worse performance wise.

Afterwards I have tried to adjust the sampling rate of the gpios but this resulted in only detecting up and down commands:

gpioCfgClock(8, 0, 0);

My latest effort was to make use of the pigpio daemon sudo pigpiod (add this command to /etc/xdg/openbox/autostart). And the following rewritten code but it does not seem to be any better.

Is there a better or more efficient way to read the serial data from our clickwheel?

On the one hand I am a bit concerned by the heat generated by the CPU even while not even running anything else but click on the other hand I kind of want to avoid adding another component as such as an Arduino if it is not necessary.

Hey, I'm probably not alone when saying this, but I'm a podcast fan, and thought that maybe you guys would like this functionality.

So I created an entry in the menu for podcasts.

Check it out, and see if its to your liking.

(First contribution to a repo that isn't mine, so if you see anything that isnt quite up to spec, let me know!)

After battling for a weekend I'm finally nearing the end of the software side of things.

The only thing that I cannot seem to get working is the search function.

I was originally having issues with actually playing any songs from my playlists until I modified the scope array in spotify_manager.py. Am I missing anything from my scope that is causing my search issues?

Here's my current scope:

 scope = "user-follow-read," \
        "user-library-read," \
        "user-library-modify," \
        "user-modify-playback-state," \
        "user-read-playback-state," \
        "user-read-currently-playing," \
        "app-remote-control," \
        "playlist-read-private," \
        "playlist-read-collaborative," \
        "playlist-modify-public," \
        "playlist-modify-private," \
        "streaming," \
        "user-read-private"

I am able to play music from my playlists, and at this stage, I'm happy to just leave it at that, but if I could get the search function working too, that would be great.

Hello, Firstly thanks for sharing this awesome project.

I receive the error below after trying to run python3 spotifypod.py This error appeared after I entered the redirected URL

Can anyone point me in the right direction to get past this?

Traceback (most recent call last): File "spotifypod.py", line 543, in <module> app = tkinterApp() File "spotifypod.py", line 88, in __init__ tk.Tk.__init__(self, *args, **kwargs) File "/usr/lib/python3.7/tkinter/__init__.py", line 2023, in __init__ self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: no display name and no $DISPLAY environment variable

Thanks

Hi @dupontgu,

could you please enable the Discussions tab in the repository settings? Instead of creating new issues, this would be a better place to ask questions.

Hello, so I tried compiling the click.c with the command supplied in the file :'gcc -Wall -pthread -o click click.c -lpigpio -lrt'. The problem is I'm getting two error messages and I don't know anything about C, so I don't know how to fix them. The errors are: click.c:160:5: warning: first argument of 'main' should be 'int' [-Wmain] int main(void *args){ ^~~~ click.c:160:5: warning: 'main' takes only zero or two arguments [-Wmain]

Can somebody help me, Pigpio is installed and I'm guessing it has to do something with the main function, but I don't know how to fix this.

Hey, I saw your video on YouTube. Really cool project! I remember my iPod mini fondly :) I remember flashing some alternative OS on it as a kid, probably breaking it with that, but that was so cool. I would write notes on it to cheat on a topography test :smile:

So I wanted to take a look at your sPod interface. But I can't seem to connect to the Spotify API.

I set the spotipy variables correctly I think:

export SPOTIPY_CLIENT_ID=123 (not my real id)
export SPOTIPY_CLIENT_SECRET=abc (not my real secret)
export SPOTIPY_REDIRECT_URI=http://foo.bar

But getting stuck after pasting the redirect URL:

$ python spotifypod.py

Do you have any idea what could be wrong here? The .cache file is being created and populated correctly as far as I can see.

Hi, Trying to get the project working on my Pi z W with waveshare screen.

I followed the instructions in the readme, but I had to install the older version of raspotify: raspotify_0.31.8.1.librespot.v0.3.1-54-gf4be9bb_armhf

First issue, on step 12 this file does not exist sudo nano /etc/default/raspotify

However it does seem raspotify is running because I can see it as a a device in my spotify app. But not sure how to edit the config now.

Second issue: I get a black screen when the desktop loads, which then eventually crashes back to desktop. When i SSH in I get this:

xset: unable to open display "" xset: unable to open display ""

When I try to run sudo -H -u pi python3 spotifypod.py I get this:

pi@pipod:~/retro-ipod-spotify-client/frontend$ sudo -H -u pi python3 spotifypod.py Traceback (most recent call last): File "/home/pi/retro-ipod-spotify-client/frontend/spotifypod.py", line 12, in <module> from view_model import * File "/home/pi/retro-ipod-spotify-client/frontend/view_model.py", line 1, in <module> import spotify_manager File "/home/pi/retro-ipod-spotify-client/frontend/spotify_manager.py", line 102, in <module> sp = spotipy.Spotify(auth_manager=SpotifyOAuth(scope=scope)) File "/home/pi/.local/lib/python3.9/site-packages/spotipy/oauth2.py", line 332, in __init__ self.client_id = client_id File "/home/pi/.local/lib/python3.9/site-packages/spotipy/oauth2.py", line 94, in client_id self._client_id = _ensure_value(val, "client_id") File "/home/pi/.local/lib/python3.9/site-packages/spotipy/oauth2.py", line 70, in _ensure_value raise SpotifyOauthError(msg) spotipy.oauth2.SpotifyOauthError: No client_id. Pass it or set a SPOTIPY_CLIENT_ID environment variable.

I did set the IDs in /etc/xdg/openbox/environment

Not sure what to do next

Hey everyone,

I want to show everyone what I did to resolve some of the major issues I've been running into during the installation @dupontgu's amazing project.

Some background: I don't have an iPod or anything, and this was all done on my Raspberry Pi 4 in a PiBoy DMG. My plan for this is to be able to launch spotipy via RetroPie.

[Errno 98] Address already in use

After going through the installation I tried running spotipy.py, but I ran into a couple of issues with the [Errno 98] Address in use. I went out of my mind thinking it was related to the UDP_PORT or even the OAuth port. Maybe it was the server address or redis? Nah, throw all of that out the window. This issue is because of a .cache not being found.

sebakitzing's post (https://github.com/dupontgu/retro-ipod-spotify-client/issues/22) led me to the right path with this issue. You can verify if the .cache folder exists by going to /retro-ipod-spotify-client/frontend and typing ls -a I was able to authorize spotipy through Midori browser, but for some reason, the .cache file would not create. I looked around and found Perelin's solution for Spotipy's OAuth (https://github.com/perelin/spotipy_oauth_demo). With a little modification to the spotipy_oauth_demo, I was able to create a cache folder to the /home/pi/ folder:

Please note: you will have to add your own client ID and secret from your Spotify Developer Dashboard. You will also need to add http://localhost:8080 to your Redirect URIs in the dashboard. I will explain the scoping modifications in the next topic.

SPOTIPY_CLIENT_ID = 'XXXXXXX'
SPOTIPY_CLIENT_SECRET = 'XXXXXX'
SPOTIPY_REDIRECT_URI = 'http://localhost:8080'

SCOPE = "user-follow-read," \
        "user-library-read," \
        "user-library-modify," \
        "user-modify-playback-state," \
        "user-read-playback-state," \
        "user-read-currently-playing," \
        "app-remote-control," \
        "playlist-modify," \
        "playlist-read-private," \
        "playlist-read-collaborative," \
        "playlist-modify-public," \
        "playlist-modify-private," \
        "streaming," \
        "user-follow-modify," \
        "user-follow-read"


CACHE = '/home/pi/.spotipyoauthcache'

sp_oauth = oauth2.SpotifyOAuth( SPOTIPY_CLIENT_ID, SPOTIPY_CLIENT_SECRET,SPOTIPY_REDIRECT_URI,scope=SCOPE,cache_path=CACHE)

With this modification, a cache folder was successfully made! I then sudo cp /home/pi/.spotipyoauthcache /retro-ipod-spotify-client/frontend/.cache This will copy the cache folder into the folder to allow spotipypod.py to work. This will also bypass the "Enter the URL you were redirected to:" prompt. Note: I use cp instead of mv because I wanted to have a backup of the cache folder in case of a disaster.

After copying this cache folder over, I ran into another issue where spotipypod.py cannot write into the cache folder due to permission issues. This can easily be resolved with sudo chomod 777 /retro-ipod-spotify-client/frontend/.cache This command opens the permission rights to the .cache folder.

After that, I was able to run spotipypod.py...into another issue.

Scope Errors

Another issue occurred when running spotipypod.py, somewhere along the line of:

https://api.spotify.com/v1/me/following?type=artist&limit=50
spotipy.client.SpotifyException: http status: 403, code:-1 - https://api.spotify.com/v1/me/albums?limit=100&offset=0:
     Insufficient client scope

This can be resolved by adding more scopes into spotify_manager.py

scope = "user-follow-read," \
        "user-library-read," \
        "user-library-modify," \
        "user-modify-playback-state," \
        "user-read-playback-state," \
        "user-read-currently-playing," \
        "app-remote-control," \
        "playlist-modify," \
        "playlist-read-private," \
        "playlist-read-collaborative," \
        "playlist-modify-public," \
        "playlist-modify-private," \
        "streaming," \
        "user-follow-modify," \
        "user-follow-read"

This fixed pretty much my scope issues.

NoneType Error

This part was tricky. As a person of many many... many playlists, some tracks become unavailable or null. spotipypod.py doesn't know what to do with these null tracks and will end up in an error before even starting. I had to modify some code around spotify_manager.py to skip null tracks. Here are the instances and their code:

!!Oh yeah before doing this, make sure to fix the playlist order first according to HerrEurobeat's post (https://github.com/dupontgu/retro-ipod-spotify-client/pull/26).

def get_playlist_tracks(id):
    tracks = []
    results = sp.playlist_tracks(id, limit=pageSize)
    while(results['next']):
        for _, item in enumerate(results['items']):
            track = item['track']
            if track is None:
                continue
            else:
                tracks.append(UserTrack(track['name'], track['artists'][0]['nam$
        results = sp.next(results)
    for _, item in enumerate(results['items']):
        if item['track'] is None:
            continue
        else:
            track = item['track']
            tracks.append(UserTrack(track['name'], track['artists'][0]['name'],$
    return tracks

def refresh_data():
  <--code skip--->
    results = sp.current_user_playlists(limit=pageSize)
    totalindex = 0 # variable to preserve playlist sort index when calling offset loop down below
    while(results['next']):
        offset = results['offset']
        for idx, item in enumerate(results['items']):
            if item['uri'] is None:
                continue
            else:
                tracks = get_playlist_tracks(item['id'])
                DATASTORE.setPlaylist(UserPlaylist(item['name'], totalindex, item['uri'], len(tracks)), tracks, inde$
                totalindex = totalindex + 1
        results = sp.next(results)

We're not done yet!

StartX

I kept running into an issue with the Xauth: xauth: timeout in locking authority file /home/pi/.Xauthority. I was not sure what could be causing it, but I read that this was not really needed and safe to deleted. So I did, I ran sudo rm /home/pi/.Xauthority I ran into another issue where when using startx, it will not launch and returns an error Cannot Open /dev/tty0 (Permission Denied) to resolve this, I had to use sudo chown pi /dev/tty0. This works, but resets when after rebooting. So I created a script:

sudo chown pi /dev/tty0
sudo chown pi /dev/tty1
sudo chown pi /dev/tty2
sudo chown pi /dev/tty3
sudo chown pi /dev/tty4
sudo chown pi /dev/tty5
sudo chown pi /dev/tty6
sudo chown pi /dev/tty7


startx

The reason why I repeated this step all the way until tty7 was because of the virtual consoles. If you already have a startx console running, using startx again will create another virtual console, which is a different ttyX set. Setting chown for 8 tty will make it safe to load in any one of these. I know this is a bit of a mess, but I have not run into any issues as of yet. I am open for optimizations and improvements.

make sure to use sudo chmod +x [yourscript].sh to allow running ./[yourscript].sh

!!Please note using sudo startx will launch it in root, which will not launch spotipypod.py at all. It'll just give you a blank screen. Just remove sudo and it should launch correctly.

After tackling these issues, I was able to load spotipypod.py at last.

Side note: During this process, I followed HerrEurobeat's other post (https://github.com/dupontgu/retro-ipod-spotify-client/pull/24) on removing emoticons from playlist names so it doesn't error. I have a couple of playlists with this and for 'future-proofing this definitely did the job.

Hey, Unless I missed it, there is no open source license for the code? If that's the case then the code is technically proprietary (I assume that's not what you want). I am not a lawyer but from what I know right now people can't legally modify, distribute, or use your code (incl. to make contributions) without your written consent each time (See this github doc).

Personally, I'd use the GNU GPL (so people can't take your code and create a closed source version) but you may prefer something else 😄

Where you would usually find playlists, albums, and podcasts I want to make a new one called Pair Audio so when it's clicked it will run subprocess.run(["btaudio-connect"]) which will run a bash command in python that connects my headphones.

My headphones already connect upon boot, But sometimes they don't or they are connected to my phone so I wanted an easy option to connect my headphones. I already have the code displaying the option but can't get it to run when clicked, I have no experience in python just messing around and looking at how the other classes get processed.

Here's what I already got working: with this code When I click on it, it freezes the program and I have to restart and it's back to normal. Any ideas?

Setup spotify API

Create a Spotify Developer Account, then create an app where you will get your Client ID, Client Secret, and create a Redirect URI

https://developer.spotify.com/dashboard/applications/

Add an app name and description can be anything

Save Client id and Save Secret id

Disable screen blanking

sudo raspi-config
Display Option > Screen Blanking > OFF / Disable

Disable Cursor and Screen Savers

Add or Create and Add this:

sudo nano ~/.bash_profile

Then:

'#!/bin/bash'

[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && startx -- -nocursor

# Disable any form of screen saver / screen blanking / power management

xset s off

xset s noblank

export SPOTIPY_CLIENT_ID='your_SPOTIPY_CLIENT_ID'

Run "spotifypod.py" with Autostart

sudo nano /etc/xdg/openbox/autostart

Then paste this before exit

#cd /home/pi/retro-ipod-spotify-client/frontend/
#sudo -H -u pi --preserve-env=SPOTIPY_REDIRECT_URI,SPOTIPY_CLIENT_ID,SPOTIPY_CLIENT_SECRET python3 spotifypod.py &
#sudo /home/pi/retro-ipod-spotify-client/clickwheel/click &

Please comment this out until I remind you to uncomment it, save the file and exit, then we are now going to make the the program that makes the clickwheel work an executable

cd /home/pi/retro-ipod-spotify-client/clickwheel
nano click.c

change #define DATA_PIN 25 to #define DATA_PIN 5

gcc -Wall -pthread -o click click.c -lpigpio -lrt

when were running "gcc -Wall -pthread -o click click.c -lpigpio -lrt" just leave it alone till you see a blinking text box

sudo chmod +x click

sudo nano /etc/xdg/openbox/environment

export SPOTIPY_CLIENT_ID='your_SPOTIPY_CLIENT_ID'

export SPOTIPY_CLIENT_SECRET='your_SPOTIPY_CLIENT_SECRET'

export SPOTIPY_REDIRECT_URI='http://localhost:8080'

Synchronize Spotify Data

Synchronizing Spotify data! Last but not least, if you want to make sure all your playlists artists, etc are synchronized every time you turn on your Spotypod, you can simply modify the script view_model.py

sudo nano view_model.py

go to line 16

#spotify_manager.refresh_devices()

spotify_manager.refresh_data()

Configure Raspotify

sudo nano /etc/default/raspotify

Uncomment and fill the following line:

OPTIONS="--username XXXXXXXX --password XXXXXXXXX"

Enter your spotify login details, In the first XXX add your email address, and in the second XXX add your password

Ex:

OPTIONS="--username [email protected] --password thisismypassword"

Paste the following

# The displayed device type in Spotify clients.
# Can be "unknown", "computer", "tablet", "smartphone", "speaker", "tv",
# "avr" (Audio/Video Receiver), "stb" (Set-Top Box), and "audiodongle".
DEVICE_TYPE="smartphone"

Entering Device id

To obtain your device id you first have to go to https://developer.spotify.com/console/get-users-available-devices/ when you go the the website your ipod may not appear connect to it using the spotify app on the device list then retry the website and it should show up

cd /home/pi/retro-ipod-spotify-client/frontend/

nano spotify_manager.py

Go to line 173 using ctrl+shift+_ and type 173 You can comment out the entire refresh_device def and replace it with

def refresh_devices():
    device = UserDevice('xxxxxxxxxxxxxxxxxxxxxxxxxxxxx','raspotify', True)
    DATASTORE.setUserDevice(device)

Replace the XXXXXXX with your device id Ex: def refresh_devices(): device = UserDevice(‘123456789','raspotify', True) DATASTORE.setUserDevice(device) After that you want to go save and exit the file then

cd ~/.local/lib/python3.7/site-packages/spotipy/

nano client.py

Go to line 1734 using ctrl+shift+_ Paste this in:

data = {"device_ids": ["xxxxxxxxxxxxxxxxxxxxxxxxxx"], "play": force_play}
    return self._put("me/player", payload=data)

Replace the xxxxxx with your device id

Post Install

Generate .cache files

sudo apt install midori

cd ~

git clone https://github.com/perelin/spotipy_oauth_demo

cd ~/spotipy_oauth_demo

sudo apt-get install python-pip python-dev

sudo apt-get install python3-pip python-dev

pip install -r requirements.txt

Before running it modify the client id and secret also your scopes in with:

nano spotipy_oauth_demo.py

Scope:

SCOPE = "user-follow-read," \
        "user-library-read," \
        "user-library-modify," \
        "user-modify-playback-state," \
        "user-read-playback-state," \
        "user-read-currently-playing," \
        "app-remote-control," \
        "playlist-modify," \
        "playlist-read-private," \
        "playlist-read-collaborative," \
        "playlist-modify-public," \
        "playlist-modify-private," \
        "streaming," \
        "user-follow-modify," \
        "user-follow-read"

Now you can save and exit the file

before reboot do the following:

sudo raspi-config

system options --> boot / auto login --> console autologin

Turn on vnc or connect a mouse to the pi, then reboot

Then you can run this program:

python spotipy_oauth_demo.py

Recommend using a Pi 4 or anything faster than a zero w, but if this is the only pi you have you should be fine but it will take a while. Your pi should be displaying a black screen then right click and click on browser then go to internet/ browser (midori). Once you did that go to http://localhost:8080/ There should be a spotify sign in page, sign in, once signed in it should redirect you to a page with gibberish code and spotify credits. Once you're on that screen exit the page and in your terminal stop running the program.

Now move your cache file to the one in spotifypod

cp ~/spotipy_oauth_demo/.spotipyoauthcache ~/retro-ipod-spotify-client/frontend/.cache

chmod 777 ~/retro-ipod-spotify-client/frontend/.cache

Once your done you can turn off vnc If you get ERNO98 already in use go to issue 30

Install Display code

ssh into the pi and edit the config file

sudo nano /boot/config.txt

Add the code below:

DIsplay code

hdmi_group=2 hdmi_mode=87 hdmi_cvt=320 240 60 1 0 0 0 hdmi_force_hotplug=1

Also you have to comment out this code:

dtoverlay=vc4-kms-v3d

Then save it, after that download the display code:

sudo apt install cmake git
cd ~
git clone https://github.com/juj/fbcp-ili9341.git
cd fbcp-ili9341

Then we want to change the native resolution to take advantage of the whole display.

nano st7735r.h

Go to line 18 which is ST7789 Change DISPLAY_NATIVE_HEIGHT from 240 to 320 After that save it and then nano into st7735r.cpp

nano st7735r.cpp

Go to line 95 with ctrl+shift+_ Comment out the line beginning with SPI_TRANSFER with // then below it add this:

SPI_TRANSFER(0x37, 0, 0);

Then exit the file then run this command:

mkdir build

cd build

cmake -DST7789=ON -DGPIO_TFT_DATA_CONTROL=24 -DGPIO_TFT_RESET_PIN=25 -DSPI_BUS_CLOCK_DIVISOR=30 -DSTATISTICS=0 -DDISPLAY_BREAK_ASPECT_RATIO_WHEN_SCALING=ON -DUSE_DMA_TRANSFERS=OFF ..

Once finished run:

make -j

After that is finished we want to make it run on boot:

sudo nano /etc/rc.local

Enter this before exit:

sudo /home/pi/fbcp-ili9341/build/fbcp-ili9341 &

Uncomment the Autostart things:

sudo nano /etc/xdg/openbox/autostart

cd /home/pi/retro-ipod-spotify-client/frontend/

sudo -H -u pi --preserve-env=SPOTIPY_REDIRECT_URI,SPOTIPY_CLIENT_ID,SPOTIPY_CLIENT_SECRET python3 spotifypod.py &

sudo /home/pi/retro-ipod-spotify-client/clickwheel/click &

Bluetooth

For bluetooth I these instructions: To install blue-alsa link To set up auto connect link

Use this to pair bluetooth device:

Please only follow the configuration instructions you already downloaded it in the previous link. link

When Done

Reboot and whenever you need to use the pod connect to it from your phone/ computer on the device list as if it were a speaker. It might take a while but it should connect eventually then you're free to exit the app and play songs from the pod.

Issues

Trying to recreate the Bluetooth settings (If you want to try and figure it out, I suggest going to #66 near the bottom there should be some links doris put) If you have any issues please feel free to comment them below 😄

Resources:

Couldn't have done this without doris, they've helped me out so much. https://hackaday.io/project/177034-spot-spotify-in-a-4th-gen-ipod-2004 https://github.com/dupontgu/retro-ipod-spotify-client https://www.youtube.com/watch?v=KciKqGX8g94 https://github.com/dupontgu/retro-ipod-spotify-client/issues/41 https://github.com/dupontgu/retro-ipod-spotify-client/issues/22 https://github.com/dupontgu/retro-ipod-spotify-client/issues/34 https://github.com/dupontgu/retro-ipod-spotify-client/issues/65 https://github.com/dupontgu/retro-ipod-spotify-client/issues/23 https://github.com/dupontgu/retro-ipod-spotify-client/issues/66 http://rsflightronics.com/spotifypod https://sigmdel.ca/michel/ha/rpi/bluetooth_n_buster_01_en.html https://github.com/dtcooper/raspotify/wiki/Play-via-Bluetooth-Speaker https://github.com/bablokb/pi-btaudio

So I almost have everything fully working now. I am down to two issues.

1. When selecting a song, it "plays" the first 3 or so seconds and then pauses on 00:03. Hitting play wont do anything and i just have to select the song again.
2. When it's playing I don't get any audio. Bluetooth is connected and shows the following for status: [Galaxy Buds2 (C0C4)]# info 60:3A:AF:4D:C0:C4 Device 60:3A:AF:4D:C0:C4 (public) Name: Galaxy Buds2 (C0C4) Alias: Galaxy Buds2 (C0C4) Class: 0x00240404 Icon: audio-card Paired: yes Trusted: no Blocked: no Connected: yes LegacyPairing: no UUID: Serial Port (00001101-0000-1000-8000-00805f9b34fb) UUID: Audio Sink (0000110b-0000-1000-8000-00805f9b34fb) UUID: A/V Remote Control Target (0000110c-0000-1000-8000-00805f9b34fb) UUID: A/V Remote Control (0000110e-0000-1000-8000-00805f9b34fb) UUID: Handsfree (0000111e-0000-1000-8000-00805f9b34fb) UUID: PnP Information (00001200-0000-1000-8000-00805f9b34fb) UUID: Vendor specific (2e73a4ad-332d-41fc-90e2-16bef06523f2) UUID: Vendor specific (a23d00bc-217c-123b-9c00-fc44577136ee) UUID: Vendor specific (b4a9d6a0-b2e3-4e40-976d-a69f167ea895) UUID: Vendor specific (e7ab2241-ca64-4a69-ac02-05f5c6fe2d62) UUID: Vendor specific (f8620674-a1ed-41ab-a8b9-de9ad655729d)

Also, how to auto connect bluetooth on startup? I have to manually connect via terminal over SSH each time.

Hey, I've been working on this project for a while now and am almost all the way through. I have only two major issues left on the software side and wanted to see if anyone could help me solve them. 1: When I try to use the search feature I get the following error and on the frontend the screen in just left with "loading..."

requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://api.spotify.com/v1/search?q=&limit=5&offset=0&type=track

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "/usr/lib/python3.9/threading.py", line 954, in _bootstrap_inner self.run() File "/usr/lib/python3.9/threading.py", line 892, in run self._target(*self._args, **self._kwargs) File "/home/pi/retro-ipod-spotify-client/frontend/view_model.py", line 155, in spotify_manager.run_async(lambda: self.run_search(self.live_render.query)) File "/home/pi/retro-ipod-spotify-client/frontend/view_model.py", line 150, in run_search self.live_render.results = spotify_manager.search(query) File "/home/pi/retro-ipod-spotify-client/frontend/spotify_manager.py", line 418, in search track_results = sp.search(query, limit=5, type='track') File "/home/pi/.local/lib/python3.9/site-packages/spotipy/client.py", line 553, in search return self._get( File "/home/pi/.local/lib/python3.9/site-packages/spotipy/client.py", line 297, in _get return self._internal_call("GET", url, payload, kwargs) File "/home/pi/.local/lib/python3.9/site-packages/spotipy/client.py", line 267, in _internal_call raise SpotifyException( spotipy.exceptions.SpotifyException: http status: 400, code:-1 - https://api.spotify.com/v1/search?q=&limit=5&offset=0&type=track: No search query, reason: None

That was me searching just 'q'

2: I can never fetch any of my playlists I'm not sure what else to put here but the only lead I have are that, if I'm actively listening to a playlist while booting it up it will have it saved. I have no clue what is the problem here but it seems like there were a lot more steps that needed to be taken around the coding for the playlist function after looking at the comments next to them.

If anyone could help fill me in on anything I may be missing or doing wrong please let me know and thank you in advance!

Not really an issue with the code, just a question, if somebody explored this idea: Does anybody know if you can fit the click wheel of a 4g classic into the front case of a 5g? Do these two share the same dimensions? I'm thinking that I might 3d print some kind of inner holder, but then I could use the 5g case with the buttons of the 4g.
