Error: Value supplied for "cookies" argument must be an array.

[mougis]

Even I didn't set param cookies :

/lib/WebSocketRequest.js:310
            throw new Error('Value supplied for "cookies" argument must be an array.');

  wsRouter.mount(/^\/chat\/.+$/g, null, (req) => {
    const connection = req.accept(undefined, req.origin, undefined);
    connection.on('message', (data) => {
      console.info({ data });
    });
  });

  wsServer.on('request', (req) => {
    wsRouter.handleRequest(req);
  });
