How to Resolve Firebase App Hosting Bad Credentials Errors

Firebase App Hosting is currently in its public preview phase, which means it still has some stability and integration issues. One notable area of concern is its integration with GitHub, where developers might encounter various challenges. Based on my experience resolving such issues, I’ve compiled a guide to share practical solutions and insights.
Let’s dive straight into the issues and their solutions!

1. Errors Encountered

Permission Denied

Permission "devconnect.gitRepositoryLinks" denied on "codebase.repository"

Bad Credentials

2. Step-by-Step Resolutions

2.1 Delete the App Hosting Backend

Use the Firebase CLI to delete your backend and its associated services:

2.2 Remove Secrets in Cloud Secret Manager

Visit the Cloud Secret Manager to remove secrets labeled with "apphosting." Make sure these secrets are not being used elsewhere in your Firebase project to avoid unexpected disruptions. google cloud secrets.png

2.3 Remove Artifacts in Artifact Registry

Navigate to the Artifact Registry in the Google Cloud Console and delete any images linked to your backend. This ensures that obsolete artifacts are no longer stored.
