The below code has recently been throwing a rootUrl error for the Google Calendar v3 API.

from apiclient import discovery 
http = credentials.authorize(httplib2.Http())
service = discovery.build("calendar", "v3", http=http)

However, the above code using the "plus" "v1" API works fine and returns the correct data. I am using the google-api-python-client version 1.5.0.

Werkzeug is saying that it's this line which is throwing the error base = urljoin(service['rootUrl'], service['servicePath'])
