KeyError: 'AccessToken' and Error Code 400 Unauthorized Request "Usage of this endpoint is not permitted under the Spotify Developer Terms and Developer Policy, and applicable law"

Hi, I was able to use this yesterday, but it seems Spotify has updated something on their end. The error message looks like this:

Traceback (most recent call last):

KeyError: 'accessToken'

I added the following line to spotify_api.py@L117:

        self.session_info = session_info_response.json()
+        print("Session info:", self.session_info)
        self.session.headers.update(

and discovered this error:
