Original GitHub issue: https://github.com/spotipy-dev/spotipy/issues/1151

Think there is a problem with how spotipy is handling strings in some functions. Atleast .track() and .playlist_tracks()
here is a code snipped im using, query is a link to a spotify playlist.

        playlist_id = query.split("/")[-1].split("?")[0]
        print(playlist_id)
        try:
            playlist = spotify.playlist_tracks(playlist_id)
        except Exception as e:
            print(f'Error while getting playlist data: {str(e)}')
            logging.error(f'Error while getting playlist data: {str(e)}')

ive tried using URL, URI and Playlist/track id

Output
An error occurred: can only concatenate tuple (not "str") to tuple

Environment:

• OS: Windows
• Python version 3.12.3
• spotipy version 2.24.0

When i put logging level in DEBUG, this is all i get when i try to call the functions:

DEBUG:spotipy.cache_handler:cache does not exist at: .cache

The stack trace shows the exact line where there is an issue, could you share that? It's basically the full error you are seeing, please copy paste everything you see

Edit: I just saw you are swallowing the error. To see the full error in here you need to either 1) remove the whole try/except

    track = spotify.track(query)

or 2) throw the error again:

    try:
        track = spotify.track(query)
    except Exception as e:
        print(f"An error occurred: {e}")
        logging.error(f"An error occurred: {e}")
        throw(e)

or 3) print the stack trace from Except https://stackoverflow.com/a/16946886/1515819:

    import traceback

    try:
        track = spotify.track(query)
    except Exception as e:
        print(f"An error occurred: {e}")
        logging.error(f"An error occurred: {e}")
        traceback.print_exc()

Ahh i see, the error is not with the function call. Looks like its with my credentials

        client_secret=SPOTIFY_CLIENT_SECRET
