What IAM role is needed to deploy `cron.yaml`?

Question

I am attempting to deploy a cron.yaml file with gcloud app deploy with a service account that has the "GAE admin" role on my project.

It is apparently not sufficient to update my cron config. It seems I need to give the service account the "project editor" role to continue.

The error I got was:

ERROR: (gcloud.app.deploy) Server responded with code [403]:
  Forbidden Unexpected HTTP status 403.
  You do not have permission to modify this app

Is there a way to update cron.yaml without requiring the "project editor" role.

Answer 1

As documented here, to deploy cron.yaml, you need the "Cloud Scheduler > Cloud Scheduler Admin role".
