Timed out waiting for Playwright response

Error message

Timed out waiting for Playwright response

What it means

The Playwright daemon did not deliver a response line within PLAYWRIGHT_RESPONSE_TIMEOUT. The wrapper treats the daemon as wedged or dead, clears self.daemon so the next call respawns it, and aborts the current action.

Solutions

1. Retry the browser action; the dropped daemon is restarted on the next request
2. Check whether the Playwright daemon process is hung or CPU-starved and restart it
3. Reduce page load or simplify the action so the daemon can answer within the fixed timeout

When it happens

Trigger: Thrown at src/openhuman/tools/impl/browser/playwright_backend.rs:166 when the library encounters an invalid state.

• Timeouts: ETIMEDOUT, deadlines, and hung requests — what actually expires when a request times out.
