Additional details
This is a tentative fix. This issue has been very difficult if not impossible to reproduce, and this is my best guess solution.
Occasionally, certain systems can send CDP commands that will fail due to the CRI websocket being closed with those commands mid-flight. This is most common with video recording ACK commands, but can potentially occur with any automation command. Prior to
[email protected], it seems as though these commands failed silently.0.33.0introduced behavior where it will throw an error in this situation. This exception was uncaught, causing Cypress to intermittently exit with code 1 even thought a given spec had succeeded.This PR:
Error: WebSocket connection closederrors similarly toWebSocket is not openandWebSocket already in CLOSING or CLOSED stateerrors: the command is enqueued, and reconnection to the CRI websocket is attemptedRuntime.addBinding,DOM.enable) from the command queue, if present, when sending them upon reconnection. This prevents them from being re-sent when iterating through the queued commands.Steps to test
Run server unit and integration tests. A reproduction of the original issue is unavailable, and confirmation on a fix will be pending user feedback.
