Error with the gather_keys_oauth2.py script

[deep-introspection]

I run the gather_keys_oauth2.py script with my client_id and client_secret but got this error:

Traceback (most recent call last):
  File "gather_keys_oauth2.py", line 81, in <module>
    server.browser_authorize()
  File "gather_keys_oauth2.py", line 36, in browser_authorize
    url, _ = self.fitbit.client.authorize_token_url()
ValueError: too many values to unpack

Any idea where it can come from?

Can you provide more details? Maybe what you are running, but please redact your personal information.

It sounds like something is being added to self.fitbit.client.authorize_token_url(), which doesn't make sense as the script is written.
