Learn how to resolve the most common problems people encounter when using the Google Drive connector.

​
Common Issues

​
Authentication Errors

Problem: Unable to authenticate with Google Drive API Solutions:
  1. Verify that the Google Drive API is enabled in your GCP project
  2. Check that your service account has the correct permissions
  3. Ensure the credentials JSON file is valid and properly formatted
  4. If using domain-wide delegation, verify the Client ID and OAuth scopes are correctly configured in Google Workspace Admin Console

​
Permission Denied Errors

Problem: “Permission denied” or “Access denied” errors during metadata extraction Solutions:
  1. Verify the service account has read access to the files and folders you’re trying to ingest
  2. If using shared drives, ensure the service account has been granted access to the specific shared drive
  3. Check if the delegatedEmail (if configured) has the necessary permissions
  4. Verify the following OAuth scopes are granted:
    • https://www.googleapis.com/auth/drive.readonly
    • https://www.googleapis.com/auth/spreadsheets.readonly (if using Google Sheets)

​
No Files Detected

Problem: Ingestion completes successfully but no files are extracted Solutions:
  1. Check your filter patterns - they might be excluding all files
  2. Verify that the driveId (if specified) is correct
  3. Ensure includeTeamDrives is set to true if you want to include shared drives
  4. Check that the service account has access to the drives you’re trying to ingest

​
Domain-Wide Delegation Issues

Problem: Domain-wide delegation not working Solutions:
  1. Verify the Client ID is correctly added to the Google Workspace Admin Console
  2. Ensure the OAuth scopes are properly configured
  3. Check that the delegatedEmail specified in the connection configuration is correct
  4. Verify that the service account has domain-wide delegation enabled

​
Google Sheets Not Extracted

Problem: Google Sheets files are not being ingested Solutions:
  1. Set includeGoogleSheets to true in your configuration
  2. Verify the Google Sheets API is enabled in your GCP project
