🔍 API Limitations

Looker Studio & Drive API

• Report Detection: Looker Studio reports don't have a specific MIME type in Drive API
• Search Strategy: Uses keyword matching (looker, data studio, dashboard, report)
• Export Limitations:
  • PDF export works for most Google Drive files
  • JSON export provides metadata only
  • Full report data extraction requires Looker Studio's native export

Workarounds

1. Better Report Detection: Name your reports with clear keywords
2. Full Data Export: Use Looker Studio's built-in export for complete data
3. Automation: Combine with other tools for complete workflow automation

🚨 Troubleshooting

Common Issues

1. "CLIENT_ID or CLIENT_SECRET missing"

• Ensure .env file exists with correct credentials
• Check that environment variables are set properly

2. "Token invalid or expired"

• Delete token file: rm ~/.looker-cli/token.json
• Run any command to re-authenticate

3. "File not found or not accessible"

• Verify file ID is correct
• Ensure you have access to the file
• Check if file was moved or deleted

4. "No reports found"

• Make sure your reports contain keywords like "looker", "dashboard", "report"
• Check if reports are in your Google Drive account
• Verify Drive API permissions
