Error with 'ws' library after updating to v8.14.2 in webpack-dev-server

Bug report

Actual Behavior

I'm encountering a "Invalid WebSocket frame: RSV1 must be clear" error when running my Vue.js application with webpack-dev-server. This issue appeared after updating the 'ws' library to version 8.14.2. The error stacktrace indicates the problem is in the 'ws' library used by webpack-dev-server.

Expected Behavior

I expected webpack-dev-server to run my Vue.js application without any WebSocket-related errors after updating the 'ws' library. The WebSocket functionality should work as expected.

How Do We Reproduce?

I'm not providing a complete GitHub repository, but the issue is reproducible by updating the 'ws' library to version 8.14.2 and running a Vue.js application with webpack-dev-server.

Please paste the results of npx webpack-cli info here, and mention other relevant information

}

The critical information is that the 'ws' library is updated to version 8.14.2, and the error occurs when running the application with webpack-dev-server. The error message mentions "Invalid WebSocket frame: RSV1 must be clear," and it appears to be related to the 'ws' library used by webpack-dev-server.
