AssertionError: No api proxy found for service "logservice"

Question

I am trying to run django in appengine locally, and I get this erro - AssertionError: No api proxy found for service "logservice"

What does this mean? Am I missing something in the setup?

I run it by the following command:

PYTHONPATH=/lib/python2.7/site-packages/  dev_appserver.py app.yaml

Full stacktrace -
