我正在尝试在node js中创建客户端WebSocket。WebSocket服务器在浏览器（firefox）中运行。代码和错误信息如下。它在浏览器中工作时在Nodejs中不工作。这是什么原因呢？我该如何解决？

编码（Node JS）：

const WebSocket = require('ws');
    const { randomBytes } = require('crypto');
        const headers = {
          Accept: '*/*',
          'Accept-Encoding': 'gzip, deflate, br',
          'Accept-Language': 'q=0.8,en-US',
          'Cache-Control': 'no-cache',
          Connection: 'keep-alive, Upgrade',
          cookie: 'key=UE2BQmTF;',
          Pragma: 'no-cache',
          'Sec-WebSocket-Extensions': 'permessage-deflate',
          'sec-websocket-key': randomBytes(16).toString('base64'),
          'Sec-WebSocket-Version': '13',
          Upgrade: 'websocket',
          'User-Agent':
            'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:72.0) Gecko/20100101 Firefox/72.0',
        };
 ws = new WebSocket(wurl, { headers });
  ws.binaryType = 'arraybuffer';
  ws.on('open', () => {
    console.log('connected', Date());
 });

  ws.on('close', () => {
    console.log('disconnected', Date());
  });

错误：

Error: Invalid Sec-WebSocket-Accept header
