Currently, we're unable to get playlist infos (and other methods I guess).

Minimal code to reproduce the error:

from spotapi import PublicPlaylist

playlist = PublicPlaylist("6zCID88oNjNv9zx6puDHKj")
results = playlist.get_playlist_info()

Full error:

Could you expand the error for me? As in access the .error property after catching it. I'll look into it soon

I tried catching the exception as you suggested.

try:
    results = playlist.get_playlist_info()
except Exception as e:
    print("Message:", e)
    print("Detail:", e.error)

Here’s what it returns:

Message: Failed to complete request.
Detail: no request url or request method provided

So it looks like the request isn’t even being built before sending.
Digging a bit into the code:

The error comes from build_request in spotapi/http/request.py, which fails because it receives no proper url/method. Tracing back, this happens in get_sha256_hash (spotapi/client.py):

resp = self.client.get(str(self.js_pack))

At this point, self.js_pack is still None (or not properly set). Converting it to str gives "None", which explains the no request url or request method provided detail.
self.js_pack is supposed to be set by self.get_session(), but get_session() fails because the expected web-player*.js script can’t be found anymore on https://open.spotify.com.

So essentially, get_playlist_info() ends up trying to call .get("None") instead of a real URL because Spotify changed the structure of their web player, so the library can’t grab the js_pack anymore.

Digging a bit into the code: The error comes from `build_request` in `spotapi/http/request.py`, which fails because it receives no proper `url`/`method`. Tracing back, this happens in `get_sha256_hash` (`spotapi/client.py`): ```python resp = self.client.get(str(self.js_pack)) ``` At this point, `self.js_pack` is still `None` (or not properly set). Converting it to `str` gives `"None"`, which explains the `no request url or request method provided` detail. `self.js_pack` is supposed to be set by `self.get_session()`, but `get_session()` fails because the expected `web-player*.js` script can’t be found anymore on `https://open.spotify.com`. So essentially, `get_playlist_info()` ends up trying to call `.get("None")` instead of a real URL because Spotify changed the structure of their web player, so the library can’t grab the `js_pack` anymore.

Was a very small fix, they changed their cdn uri.
