Original GitHub issue: https://github.com/spotipy-dev/spotipy/issues/686

spotipy version = 2.18.0

client_credentials_manager = SpotifyClientCredentials(SPOTIPY_CLIENT_ID, SPOTIPY_CLIENT_SECRET)
api = spotipy.Spotify(client_credentials_manager=client_credentials_manager)

this works

random_artists = ["0C8ZW7ezQVs4URX5aX7Kqx", "1SupJlEpv7RS2tPNRaHViT"]
recommendation = api.recommendations(seed_artists=random_artists)
for track in recommendation['tracks']:
  print(track['name'], '-', track['artists'][0]['name'])

but this doesn't

random_tracks = ["-0kcet4aPpQ", "0RNDeBcIK00"]
recommendation = api.recommendations(seed_tracks=random_tracks)
for track in recommendation['tracks']:
  print(track['name'], '-', track['artists'][0]['name'])

or a combination of both doesn't work either

recommendation = api.recommendations(seed_artists=random_artists, seed_tracks=random_tracks)
for track in recommendation['tracks']:
  print(track['name'], '-', track['artists'][0]['name'])

Error is :

@lohriialo your random_tracks don't seem to be valid?

See an example in the tests

Hmm i'm not sure docs says to give a list of tracks IDs, those are valid track IDs, so I just pass those tracks just as artist list
