"spotipy.exceptions.SpotifyException: http status: 400, code:-1" when using recommendations() from spotipy API

Question

I'm trying to build a program with spotipy that will create a custom spotify playlist. I succeeded to get three lists with the current_user_recently_played() function that contain the recently played genres, artists and tracks. according to that three lists i'm trying to use the spotipy.client.Spotify.recommendations in order to get recommendations by those three parameters. the func description from the spotipy documentation

this is the code:

 recommendations = spotify.recommendations(seed_artists=artists, seed_genres=genres, seed_tracks=tracks)

when:

artists = ['5eAWCfyUhZtHHtBdNk56l1', '6mdiAmATAx73kdxrNrnlao', '0epOFNiUfyON9EYx7Tpr6V']   
tracks = ['31RTFPrB7wmYBhlkM2ILXG', '3nlGByvetDcS1uomAoiBmy', '55N8cxpE1QDoeaaNqUnoZ2']
genres = ['rock', 'metal', 'punk', 'grunge', 'pop']

When i'm runing the code I get this error:

HTTP Error for GET to https://api.spotify.com/v1/recommendations returned 400 due to invalid request

During handling of the above exception, another exception occurred:

Figured that out... you can't use more than five seeds.
