Cause (Documented platform behavior): The cloud client maps HTTP 401 to an invalid-key CloudBrowserAuthError, 403 to a subscription-status error, and the @sandbox decorator requires BROWSER_USE_API_KEY before executing.
Fix status: documented_behavior
Limitations:
- Source is the published browser-use 0.13.10 wheel from PyPI; behaviour may differ in other versions.
- Not reproduced in this session.
Other error fragments:
- Access forbidden. Please check your browser-use cloud subscription status.
- BROWSER_USE_API_KEY is required
- Timeout while creating cloud browser. Please try again.
