We have same problem. Weird thing is, it used to work, and this error started showing up without any relevant package.json changes

[llehn]

We changed tests to run in Chrome instead of ChromeHeadless and the issue vanished.

Just wondering if there's any update on this issue?

[SanthoshBanavath]

Is there any fix or update on this?

As a workaround it helped to downgrade socket.io to 4.7.0.

...
    "overrides": {
        "socket.io": "4.7.0"
    }
}
