StringProto instance has no attribute 'set_login_url'

Question

I have updated to version 1.2.5 of the Python appengine SDK. However, now I am getting the following error:

Traceback (most recent call last): 
  File "C:\Program Files\Google\google_appengine\google\appengine\ext 
\webapp\__init__.py", line 507, in __call__

\apiproxy_rpc.py", line 111, in CheckSuccess 
    raise self.exception 
AttributeError: StringProto instance has no attribute 'set_login_url'

The code it is referring to is:

url = users.create_login_url("/")

Any idea as to why I am getting this error? It was working before the update. I posted this on the App Engine Google group with no luck.

Answer 1

Are you sure you have the current code for everything? set_login_url is defined in google/appengine/api/user_service_pb.py

That method (which is part of the CreateLoginURLRequest class) is new in 1.2.5 and was checked in with r73.

Apologies if this has already been checked.

Answer 2

I fixed the issue by completely uninstalling the SDK and then re-installing it. A Repair and installation over the previous directory does not guarantee a clean update.
