This is a public playlist

Okay, it seemed strange to me because I had just tried with 2 playlists yesterday... but I did manage to reproduce your error.
By the way, shouldn't this be in the issues section? I hope I haven't configured something incorrectly!

Indeed, when trying to download or inspect a playlist using the CLI (which is where I usually solve most problems), I got the same error:

2025-11-15 21:21:23,652 [INFO] SpotifyAPI: Fetching playlist data: https://open.spotify.com/playlist/37i9dQZF1DX3R7OWWGN4gH?si=d262b75de0d0450c
2025-11-15 21:21:24,797 [ERROR] spotipy.client: HTTP Error for GET to https://api.spotify.com/v1/playlists/37i9dQZF1DX3R7OWWGN4gH with Params: {'fields': None, 'market': None, 'additional_types': 'track'} returned 404 due to Resource not found
2025-11-15 21:21:24,797 [ERROR] SpotifyAPI: Error fetching playlist data: http status: 404, code: -1 - https://api.spotify.com/v1/playlists/37i9dQZF1DX3R7OWWGN4gH?additional_types=track:
 Resource not found, reason: None

Originally we extracted the data from the Spotipy() client, using its .playlist() method. That method seemed to work the same with the playlist id as with the URL, so for simplicity we passed the URL directly:

    @lru_cache(maxsize=32)
    def _fetch_playlist_data(self, playlist_url: str) -> dict:
        try:
            self.logger.info(f"Fetching playlist data: {playlist_url}")
            return self.sp.playlist(playlist_url)
        except spotipy.exceptions.SpotifyException as e:
            self.logger.error(f"Error fetching playlist data: {e}")
            raise ValueError("Playlist not found or invalid URL") from e

The solution I can think of (and which I will extend to all Spotify client query methods) is to parse the URL to obtain only the ID (for track, album, artist, or playlist)... I've tested it and it seems to work well. We'll try two methods just in case, one using urllib.parse and the other using regex. For now, I'll stick with the regex method:

    def _extract_spotify_id(self, url: str) -> Optional[str]:
        """
        Extrack the ID from a Spotify URL. It uses regex.

        Args:
            url (str): Spotify URL of a Track, Artist, Album or Playlist
        
        Returns:
            id (Optional[str]): id of the item or None if not found
        """
        pattern = r"(?:track|artist|album|playlist)/([A-Za-z0-9]+)"
        match = re.search(pattern, url)
        return match.group(1) if match else None

    @lru_cache(maxsize=32)
    def _fetch_playlist_data(self, playlist_url: str) -> dict:
        """Fetch raw playlist data from the API.
        
        Args:
            playlist_url: Spotify URL or URI for the playlist
            
        Returns:
            dict: Raw playlist data from Spotify API
            
        Raises:
            ValueError: If playlist is not found or URL is invalid
        """
        try:
            self.logger.info(f"Fetching playlist data: {playlist_url}")
            playlist_id = self._extract_spotify_id(playlist_url)
            if not playlist_id:
                raise ValueError("Invalid playlist URL")
            return self.sp.playlist(playlist_id)
        except spotipy.exceptions.SpotifyException as e:
            self.logger.error(f"Error fetching playlist data: {e}")
            raise ValueError("Playlist not found or invalid URL") from e

I hope this solves the problem and that it will be available in the next release! We'll create a pull request if you prefer to clone the repository and build directly!

@giwty if you can, could you create an issue about this?

[giwty]

Thanks for the quick reply, will wait for next release to try this out.
Looks like creating new issues is disabled for this project ? that's why i created it as a discussion.

Hey, thanks for letting me know... not only had I put the templates in Markdown (which apparently isn't recognized except as suggestions), but the YAML files were also misconfigured 😅... It's fixed now!

I have some free time, I have to take advantage of it!
