Describe the bug
Fetching features for a list of song id's gives me a python error

Your code

credentials = SpotifyClientCredentials(
    client_id=client_id,
    client_secret=client_secret)

spotify = spotipy.Spotify(auth=credentials.get_access_token())

song_ids = ['7uZNffK8arChpeCVV6ooDr', '3ehKHnuLaIIOVhAtgUi5wD', '5mRDK6F8gJjt23LL3Iy3Hp', '34NNeV9jfgNgaALgUr0u9V', '1vQ92830bxiBcIhpUj4qrn', '53vJGKfm25KT22hXvCTU4I', '7EAM4KXX04XU9H0VwxtqyE', '2WIuQNRwLRuBJY9tkLMGpN', '4pk4W1VtvrQO3so7LGvtIl', '55jiDN7K7OtbBANR4vlTuQ', '4tztBBPjkqzxfPG8jQ1Rh5', '79FSutPOikJHaWscFTtymd', '6mCR84oWk19XCfGTCL9Wee', '0AhRPDuVwHkLAACbPXidb3', '40AYRnDKhhrH4JZO4KS9Dj', '4GWnDzLsP31cul3K88pKVn', '2YBnNbMOUUSkqncnQgkqST', '70siNXjjzwMZ3WHPSaPz0P', '13ZsIACMHaWi8F1va20QZW', '46GI18GhwT31iAZfgCR2gF', '4smUfRf4r4zIgvPW0W0ILN', '2GTi76fD1RgO34wDxRaeXB', '02aQOlXR3R2uQpatJqt7v3', '12KmwMaA5q76JdmFfE0uL9', '1Ag7wxTGvCK4Vqw5PPqdle', '3qC3qmZNDXu62hc8YbhWsy', '1t7ToVITrs0LkMwRC2XEON', '1GfZuvW3k5Ci52eNTgOkTw', '42U2KTNRv0KSDnkQNiQjbo', '5JUbrNZTDZu77uqy8R9GYy', '6A2TqxtIW1On4gXlCXTlKX', '68jajO3lJDSOsKSyXiEmJl', '5DMgHQS7W53azRdFnXHH6d', '137O1R5exWz3qxpq2Mtdib', '5j5xz0zpIfNcS1FZwOZo2i', '065mLOJfAqeHZ162rIx5YB', '4Pb7Mg18H4S0jCGgH6bIIq', '5QyEPCvvT2Qmded0BZ7GGG', '7MKYNJAjqIRkW9S71GSwAJ', '2NBrtRd7wE6JYLPbnHkTOO', '0FvYOpdqf3hO9pK88716uh', '6JoxpsF0yzjRcZyrPJPfXY', '29zZGZm12irXsA1mf2rlGo', '3aXM9duTbQJDnNrOzh8cb6', '3SihC64kvAsvnBPyDgMW3y', '00Tdk7uw0KudbIrdg0niLi', '62vHkhd3HgdzLHmkgwsxzZ', '4BBzCCib0j9qMneACP7HeE', None, '6g1NlCpW7fgqDnWbCCDrHl', '1A29M5wR1kbCuzc9CTeU6y', '7xMoXPnN5PwXFfvhynj02P', '2pMSrjYVTUP2qyUBj6OFhj', '1hPYVFjQ3Dgv1PK3NytIIb', '5YHmAO5OSZqyvs0X9O3hEK', '45HrXgH40Jbq6bxh165aI1', '3FE6Xwjn3z8W3wlhIgpFUD', '3ljB23GWqz8h5c4rAIUkL2', '2an7yYoSs5T3AFO0TFHohj', '1oetTjzloPtOPMSQmw6EP3', '1OIap2AeiVhAavWyRKTSba', '2W0p4sfCxY6fUXS3y01hVw', '2b3nvCZ4dwBfAvDWWIG4H8', '3JV8mp0SJ7YmSeYjE8NMLZ', '6vOCcO3YjdfaXkaFpcMtPz', '5ZwTAZe3enscONgoMKTd9Y', '21ycThF1ruVSPyaw8BkRHM', '5RsbvJQ6q82oc9hyaLEmmV', '3L2W7SDk3beBYEfOBblWCG', '5bw3ANysdLNdRl8wZfunVp', '5fDydQ2X61CcVtt48UXMNb', '1fjCRAIaEABA1bQzgYYtpd', '0HuJhVu0fMc26n8kcPwVTc', '6PUIzlqotEmPuBfjbwYWOB', '2oKPjUNx0kAj9JlPABZFxw', '3bzqd8quMDaCt7pLb98SHS', '4dWuPULnSVkzJC0wDFlAxS', '0gIZXqW6s7zSf21bFrzI29', '13gD7RyWE7ZOEoxfGAXm1B', '352zfYbDFG8sxkmOAhVeuj', '5Khth2Cb94VH6O1T4K0lqK', '3QEoWceTh3j9dCJHwmuSj1', '5SMYN4lHZduUD8SQ0TEHj2', '7nkOH6CQX02HDuXKWYuh1I', '6UUhruYdm0bgynD8ERUHmL', '7jX4E7JPe9CqLexMobIWNY', '6GVtybBya8EzI4rC9P7FQM', '2N2Mp4HjnYcmrZ2YqrKedy', '4tQMd2go7qhp914CTHKdql', '2B8eAzF1rlTOLynq5zgXsG', '1nsvulFIVKrfPMM0592qCe', '0O3ejIM41qOAxJBizTEADf', '1sqN9hAFDFYMzTE1JLhPaS', '58KRLZxN7H9ZYoMyWiWAj6', '3g1yJqVEx6FKlUzy2GL6Id', '2emXGZyrkTEfy383K3hDhG', '6UEJtAnGHnK5tVhoPHD6tU', '4IWLawtdMznqdOnbOR9cWW', '0R7gbDisCJLii7ByE2rHJh', '0XtDMRff7VOvKQYedTUHKt']

features = spotify.audio_features(song_ids)

Expected behavior
I expected to get the features for the song id's I queried

Output

File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/spotipy/client.py", line 1248, in audio_features
tlist = [self._get_id("track", t) for t in tracks]
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/spotipy/client.py", line 1248, in
tlist = [self._get_id("track", t) for t in tracks]
File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/spotipy/client.py", line 1467, in _get_id
fields = id.split(":")
AttributeError: 'NoneType' object has no attribute 'split'

Environment:

  • OS: Mac
  • Python version: 3.8
  • spotipy version: 2.13
  • your IDE: PyCharm

Additional informaton:
This worked perfectly fine for me previously, so I'm wondering if anything happened with Spotify's web api?

EDIT:
I have managed to figure out that this only happens on some of my playlists, for example the id's in the following playlist:
spotify:playlist:5YtuU88z2sdmp0yfuJWytn (the one posted above)

Good catch, but why is one of the songs id's None after calling playlist_tracks('spotify:playlist:5YtuU88z2sdmp0yfuJWytn', fields='items.track.id')?

It looks like it is a local track and being unknown to spotify, doesn't have an id
