如何修复 Node js 中的错误 Invalid Sec-WebSocket-Accept 标头？

Question

I am trying to create client websocket in node js. The websocket server is running in the browser(firefox). code and error message are below. It isn't working in Nodejs while it's working in the browser. what's the reason for this? how can i solve?

Code(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());
  });

Error:
