BrowserUse example not working

Start by reproducing the BrowserUse Python example at the linked Browserbase documentation page and compare its Playwright error-handling path with the logged traceback. Investigate why the dispatched message lacks the expected error key; done means the example runs without this KeyError and the failure, if any, is reported normally.

Hi,

I was trying to follow the browseruse example here

The code errors with keyerror pointing to some error handling in playwright. Logs and error below. Thanks!
