Need help with Django/Tweepy OAuth2UserHandler error: 'Missing required parameter [code_verifier].'

[MatthieuDurand08]

Hello guys,

I'm trying to allow users to connect their Twitter account with my Django app using tweepy (OAuth2UserHandler) this way:

#views.py

oauth2_user_handler = tweepy.OAuth2UserHandler(
    client_id=client_id,
    redirect_uri=redirect_uri,
    scope=scope,
    client_secret=client_secret,
)

class TwitterLoginView(LoginRequiredMixin, View):
    def get(self, request, *args, **kwargs):
        return redirect(oauth2_user_handler.get_authorization_url())

class TwitterCallBack(LoginRequiredMixin, View):
    def get(self, request, *args, **kwargs):
        access_token = oauth2_user_handler.fetch_token(request.build_absolute_uri())
        (...)

#error:
InvalidClientIdError: (invalid_request) Missing required parameter [code_verifier].
for this line :  access_token = oauth2_user_handler.fetch_token(request.build_absolute_uri())

(I'm a beginner I know the code is dirty sorry)

The thing I really don't understand is that everything works well locally (with a different uri of course) but not in production on my EC2 instance (I use Docker and Django-Cookiecutter). Someone would have any idea?
