AppEngine Flex Deployments suddenly failing with 405 Method Not Allowed

[richardjg]

An AppEngine Flex deployment that had been working happily for years suddenly stopped working today with the error:

ERROR: (gcloud.app.deploy) Error Response: [13] 
Flex operation projects/getregistered-production/regions/us-east1/operations/e9deb56a-1fe3-457a-957b-549418a0a283 
error [INTERNAL]: An internal error occurred while processing task /app-engine-flex/insert_flex_deployment/flex_create_resources>2023-03-09T23:48:16.103Z12239.ue.2: 
405 Method Not Allowed

[html omitted]HTTP Method 'POST' is not supported by RpcServer[html omitted]

This is using a pre-build image.

Is AppEngine having an issue with deployments today?

Hi @richardjg ,

Is this still occurring? If so, could you please provide a reproducible steps to further check what's happening on your deployment.
