allauth.socialaccount.providers.oauth2.client.OAuth2Error: Error retrieving access token: b''

My FacebookLogin view as follows, I installed nginx to serve https in localhost etc. : 

class FacebookLogin(SocialLoginView):
    adapter_class = FacebookOAuth2Adapter
    client_class = OAuth2Client
    callback_url = "https://localhost"

The popup window opens and when I give permission to the app, popup windows closes and the HTTP 500 error occurs as the above trace.

I have solved the problem, and the error is not relevant to rest-auth nor allauth. It is relevant to Facebook. The problem was missed backslash for callback_url. In that case Facebook graph api backend gives 500 error without any error messages. It gives just an empty response so, it is not possible to figure out what's going on.
