400 Error from Get Recommendations

Context

I use the recommendations api all the time. In a new code base, it fails and I can't figure out why. The code is the same.

Error message

spotipy.exceptions.SpotifyException: http status: 400, code:-1 - https://api.spotify.com/v1/recommendations?limit=20&target_valence=0.3:

Code snippets

recommendations = self.current_user.recommendations(limit=20, market='US', seed_artist='4NHQUGzhtTLFvgF5SZesLK',target_valence=.3)

Auth function

@app.route("/auth-callback")

def auth_callback():

code = request.args.get("code")

auth.get_access_token(code, as_dict=False)

try:

if current_user.current_user()["display_name"] not in ['kornacle','Mashmia']:

mp.track(current_user.current_user()['display_name'], 'Login Successful')

except:

pass

login_user(current_user)

return redirect(url_for('login'))

Hey @mashmia - thanks for posting that code sample!

I noticed that you have spelt the seed_artists parameter in the singular. Does it help if you change that to seed_artists, and pass it an array rather than a single string? Here is an example using the client credentials OAuth flow:

import spotipy from spotipy.oauth2 import SpotifyClientCredentials sp = spotipy.Spotify(auth_manager=SpotifyClientCredentials(client_id="client_id", client_secret="client_secret")) reccos = sp.recommendations(limit=20, market='US', seed_artists=['4NHQUGzhtTLFvgF5SZesLK'],target_valence=.3)

Thanks Josh. I updated to plural and still not having success.

Somewhat different error message:

spotipy.exceptions.SpotifyException: http status: 400, code:-1 - https://api.spotify.com/v1/recommendations?limit=20&target_valence=0.3: invalid request, reason: None
