Playwright daemon response id mismatch

Error message

Playwright daemon response id mismatch

What it means

A response did arrive from the Playwright daemon, but its id field does not equal the request id that was sent. That means replies are out of order or the daemon state is corrupt, so the response cannot be matched to this call and the request is rejected.

Solutions

1. Retry the action so a fresh daemon and request id are used
2. Ensure only one request at a time is multiplexed over the shared daemon connection
3. Restart the Playwright daemon if mismatched ids recur
