Getting several tracks audio features returning error 429

[ThamiFromDoukala]

Hello, 

I'm working on a web app, I code in Python and using Spotipy. I want to build a large datasets for my saved tracks that retrieves different track features. For that I'm using the audio_features as well. When going through my code line, it returns error code 429 (max retries achieved). I even tried to create a new spotify app and try with new credentials but still. Here's my code below for reference. 

def build_saved_tracks_dataset(limit_step=50):
    user = spotipy.Spotify(auth_manager=SpotifyOAuth(client_id='client_id',
                                                     client_secret='client_secret',
                                                     redirect_uri='http://localhost:8080',
                                                     scope='user-library-read'))
    

    tracks = list()
    offset = 0
    while True:
        response = user.current_user_saved_tracks(limit=limit_step,
                                                            offset=offset)
        if len(response['items']) == 0:
            break
        offset += limit_step
        
        track_ids = [item['track']['id'] for item in response['items']]
        artists_id = [item['track']['artists'][0]['id'] for item in response['items']]

        audio_features = user.audio_features(track_ids)
        artists = user.artists(artists_id)
        
        
        for track, artist, audio_feature in zip(response['items']['track'], artists, audio_features):
            genres = ','.join(genre for genre in artist[0]['genres'])
            # tracks.append(id, name, artist, tempo...) Populating my dataset
            pass

    return tracks

Note that if I delete the audio_features line and ll he parameters in the dict that comes with it, the code works, so its weird that the limitation is only applied to audio_features.

I gave it 24 hours before trying again and same

Any idea on how to resolve this ? 

Thanks !
