Diagnosing error in deploying GAE flex app

I've been using GAE flex for awhile now, and all of a sudden my deploy process ends on the command line with:

ERROR: (gcloud.app.deploy) Error Response: [4] Flex operation projects/MY-PROJECT/regions/us-central1/operations/xxx error [DEADLINE_EXCEEDED]: An internal error occurred while processing task /appengine-flex-v1/insert_flex_deployment/flex_create_resources>2019-09-04T21:29:03.412Z8424.ow.0: Gave up polling Deployment Manager operation MY-PROJECT/operation-xxx.

My logs don't have any helpful info. These are relevant logs from the deployment:

The instance exists in the console and appears to be running, but it just returns a 404. The code runs fine locally.

Any ideas for how to diagnose what is going on?

I wonder if Google reduced a default deadline since the current deadline appears to be 4 minutes and my build has always taken longer than 4 minutes.

I figured this out and it is kind of a crazy Google Cloud bug. TL; DR -- Don't use Google Cloud Organization Policy Constraints.

Here is what happened according to my best understanding:

  • For my Google Cloud project, I picked the us-central region.
  • About 6 months ago I set a Google Cloud policy constraint for my organization so that I would use only US-based resources. This set a policy that allowed US resources that existed at that time.
  • My recent deploys of my flex app were being deployed to the us-central1-f zone. I believe Google picked the zone and I don't have control over that.
  • The us-central1-f was not allowed by my location policy because that zone did not exist at the time I set my location policy.
  • This caused my deploy to crash with the unhelpful error message in my question.

The way I figured this out was that I deployed Google's hello world flask app, and when deploying that app, I received a more helpful error message that allowed me to understand the problem.
