Can I verify OpenID authentication on Google App Engine on a development server?

Question

I try OpenID to support Google App Engine in a small project that I have on my machine, but when I call:

users.create_login_url(federated_identity = provider_url)

I get this error:

google_appengine/google/appengine/api/user_service_pb.py", line 178, in ByteSize
    n += self.lengthString(len(self.destination_url_))
TypeError: object of type 'NoneType' has no len()

provider_url https://www.google.com/accounts/o8/id

any clue?
