I didnot find any discussion or Issues regarding this . Actually this error occurs when user pass value of code into any of one.
I think same issue persist for other views also.

class GoogleLogin(SocialLoginView):
    adapter_class = GoogleOAuth2Adapter
    callback_url = settings.GOOGLE_AUTH_CALLBACK_URL
    client_class = OAuth2Client

class GitHubLogin(SocialLoginView):
    adapter_class = GitHubOAuth2Adapter
    callback_url = settings.GOOGLE_AUTH_CALLBACK_URL
    client_class = OAuth2Client

• Solution
  It can be solved by removing scope argument while calling self.client_class i.e class OAuth2Client(object): from django-allauth package . Actually scope was removed in 0.62.0 that a long time ago .
