Chatbot Test + Preview BLANK

[limdog]

Issue: Builder works fine, but chatbot preview/test pages are blank — only “Made with Typebot” shows. Happens on both v3.7.1 and v3.8 using Docker on macOS.

What I’ve tried:

• Fully configured .env with Mailtrap, Postgres, Redis, secrets
• Set NEXT_PUBLIC_API_URL, NEXT_PUBLIC_VIEWER_URL, etc
• Published bot, used correct public ID in URL
• Tried both default and custom ports
• Viewer logs show no errors
• Browser console only shows MetaMask noise
• API endpoint (/api/flows/) returns valid data

Expected: Chatbot loads at localhost:8081/ Actual: Page is blank. No bubbles, no errors.

Please advise.
