🔧 Troubleshooting

"credentials.json not found"

→ Download it from Google Cloud Console, rename it, put it in project folder

"Access blocked"

→ Make sure you enabled both Gmail API and Drive API

Browser doesn't open

→ Copy the URL from terminal and paste in browser

"Invalid grant"

→ Delete token.json and run again to re-authenticate

Connection error in Streamlit

→ Make sure gmail_drive_rest.py is still running in another terminal
