Can't authenticate Google Cloud with Service Key on GitHub Actions

I have the service account key JSON stored as a secret, no errors in the file. Yet every time I run the action it keeps complaining about an unexpected token. What is wrong?

Error: google-github-actions/auth failed with: retry function failed after 1 attempt: failed to parse service account key JSON credentials: unexpected token  in JSON at position 0

Service Account Key format:

{
  "type": "service_account",
  "project_id": "",
  "private_key_id": "",
  "private_key": "-----BEGIN PRIVATE KEY-----\\n-----END PRIVATE KEY-----\n",
  "client_email": "",
  "client_id": "",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://oauth2.googleapis.com/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": ""
}

Workflow:

- id: 'auth'
      name: 'Authenticate to Google Cloud'
      uses: 'google-github-actions/auth@v1'
      with:
        credentials_json: $GOOGLE_CREDENTIALS
    - id: 'upload-file'
      name: 'Upload report to Google Cloud'
      uses: 'google-github-actions/upload-cloud-storage@v0'

CodePudding user response：

maybe a typo in the auth step? Just try:

- id: 'auth'
      name: 'Authenticate to Google Cloud'
      uses: 'google-github-actions/auth@v1'
      with:
        credentials_json: ${{ secrets.GOOGLE_CREDENTIALS }}

instead of:

      with:
        credentials_json: $GOOGLE_CREDENTIALS
