This suddenly started happening a few weeks ago and I have not been able to figure out what happened. My best guess is that updating gcloud components caused it since nothing else changed.
try changing:
applications = ndb.get_multi(application_keys)
to
applications = ndb.get_multi([key for key in application_keys if key])
it looks like one of your keys is None
