Troubleshooting

Authentication Errors

• Ensure your service account email is shared with the spreadsheet you're trying to access
• Verify that the Sheets API is enabled in your Google Cloud project
• Check that the credentials file path is correct and the file is readable

Permission Errors

• Make sure the service account has been granted access to the spreadsheet (share it with the service account email)

API Quota Errors

• Google Sheets API has rate limits. If you hit them, wait a few minutes before retrying
• Consider implementing exponential backoff in your client application
