Hello,

I have written a little test script, that is supposed to like the currently playing song. The current problem I am facing is, that song.like_song(track_id) will raise spotapi.exceptions.errors.SongError: Could not like song.

Based on the error logs, it appears the library is sending the wrong variable name in the GraphQL payload. The API expects libraryItemUris but the library sends uris.

Environment:

OS: Windows
SpotAPI Version: 1.2.7

song.py line 278 :

"variables": {"uris": [f"spotify:track:{song_id}"]},

should be:

"variables": {"libraryItemUris": [f"spotify:track:{song_id}"]},

Code:

from spotapi import (
    Login,
    Config,
    NoopLogger,
    PrivatePlaylist,
    JSONSaver, Song, PlayerStatus
)

config = Config(
    logger=NoopLogger()
)

instance = Login.from_saver(JSONSaver(), cfg=config, identifier="*****************************")

playlist = (PrivatePlaylist(instance).get_library().get("data").get("me").get("libraryV3").get("items")[0]
            .get("item").get("_uri"))  ##uri of the liked songs playlist.

status = PlayerStatus(instance)
player = status.state

liked_songs_playlist = PrivatePlaylist(instance, playlist)
# liked_songs_playlist.create_playlist(name="test playlist") # Test if I am logged in -> playlist is created = logged in

track_uri = player.track.uri  # e.g. "spotify:track:3n3Ppam7vgaVa1iaRUc9Lp"
track_id = track_uri.split(":")[-1]  # -> "3n3Ppam7vgaVa1iaRUc9Lp"

song = Song(liked_songs_playlist)
song.like_song(track_id)

instance.save(JSONSaver())

Console error
