Google Cloud Container Builder fails to push images to container registry

问题

My cloud builds used to push result images to GCR, but something happened and I am seeing this in my build logs:

PUSH
Pushing gcr.io/$PROJECT_ID/zookeeper:9c6def09508c52b9f364aa4751d520c79690e54c
The push refers to a repository [gcr.io/$PROJECT_ID/zookeeper]

174a611570d4: Layer already exists
name unknown: Buckets($PROJECT_ID,artifacts.$PROJECT_ID.appspot.com)

The above repeats for every layer. I'm not sure what happened. I recently revoked and re-logged-in with gcloud auth. But other gcloud commands work and gsutil works and shows that the above buckets exist. Permissions look good, but maybe I am missing something?
