ERROR: (gcloud.app.deploy) INVALID_ARGUMENT: unable to resolve source

Question

I am trying to deploy a go 1.11 runtime that used to work, but recently I've been getting: ERROR: (gcloud.app.deploy) INVALID_ARGUMENT: unable to resolve source errors.

Nothing in my app.yaml has changed, and the error message isn't helpful to understand what the issue could be. I ran it with the --verbosity=debug flag and get:

Any advice would be useful, I also tried it with gcloud beta, I rotated my credentials and was of no use. My user has Owner role, but I added individually all the roles that might be necessary

Answer 1

Try disabling and enabling the Cloud Build API in your project so a new service account is created, then try to deploy again.

This ensures that Cloud Build has permission to start builds (the service account name should look like [email protected]).
