I wrote a service for one of my projects to create and start "Dataflow-Job-Templates" from "Google App Engine", combined with "Task Queues".
The Templates can only be started, if they were created successfully beforehand. I just realized, that sometimes, the following error is thrown. Is this a problem in gae or is there anything I can do to prevent this? I haven't seen this before and after some tries, the templates seem to run.
The stacktrace:
