ERR_STREAM_WRITE_AFTER_END write after end

Created by: guillaume-at-palo

I often get the following error when I run tests through cypress. I suppose that connections from the browser are reseted and so the socket is closed.

error: write after end {"name":"Error [ERR_STREAM_WRITE_AFTER_END]","stack":"Error [ERR_STREAM_WRITE_AFTER_END]: write after end

Testing if socket is open in ws-incoming.js seems to solve the issue

    proxyReq.on('response', function (res) {
      // if upgrade event isn't going to happen, close the socket
      if (!res.upgrade && socket.readyState === socket.OPEN) {
        socket.write(createHttpHeader('HTTP/' + res.httpVersion + ' ' + res.statusCode + ' ' + res.statusMessage, res.headers));
        res.pipe(socket);
      }
    });

Is it the right way to solve the issue ?
