问题 I am using cloud Firestore database and I have 'users' collection on my root database and in it there are all the users documents (named as the uid) and inside it the data I collect.

问题 I'm using Google Cloud Build to do a deployment to Firebase Hosting when a commit is on master. I'm using the Firebase Cloud Builder, deployed to my project.

Here is the step in my cloudbuild.yaml that fails: - name: gcr.io/$PROJECT_ID
