I apologize if this is the wrong place for this, but I am trying to deploy a node.js app to the App Engine with a cron job. I added the cron.yaml file to the app and deployed, but the job never gets executed.

cron.yaml:

cron:
- description: test cron job
  url: /api/crontest
  schedule: every 1 mins

The endpoint exists in my app and I can hit it directly from the browser, but it never executes from the cron. The only thing I see in the logs is an occasional cron: unrecognized service, but it does not correspond with the one minute frequency.

What am I missing? Is cron supported in the platform?
