我的 server.js 文件中有以下代码，用于一个使用 express 作为后端的 Web 应用程序和一个它所服务的内置 create react 应用程序。

require('rootpath')();
const path = require('path');
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const cookieParser = require('cookie-parser');
const cors = require('cors');

app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.use(cookieParser());

app.use(cors());


app.use(function(req, res, next) {
  res.header("Cross-Origin-Embedder-Policy", "require-corp");
  res.header("Cross-Origin-Opener-Policy", "same-origin");
  next();
});

// Have Node serve the files for our built React app
app.use(express.static(path.resolve(__dirname, 'build')));

// file api routes
app.use('/accounts', require('./accounts/accounts.controller'));

// file api routes
app.use('/files', require('./files/files.controller'));


// All other GET requests not handled before will return our React app
app.get('*', (req, res) => {
    res.sendFile(path.resolve(__dirname, 'build', 'index.html'));
});

// start server
const port = process.env.PORT || 2002;
app.listen(port, () => console.log('Server listening on port ' + port));

这里的问题是我需要这段代码才能进行 ffmpeg 文件上传，否则会引发 SharedArrayBuffer 错误：

   app.use(function(req, res, next) {
      res.header("Cross-Origin-Embedder-Policy", "require-corp");
      res.header("Cross-Origin-Opener-Policy", "same-origin");
      next();
    });

但是，当我留下这段代码时，我的程序的另一部分会发生故障，它会从 s3 获取预签名的 url 并播放音频。每当我从我的 s3 存储桶播放音频时，都会出现以下问题：

ERR_BLOCKED_BY_RESPONSE.NotSameOriginAfterDefaultedToSameOriginByCoep

s3 代码是这样的：

function getTemporaryURL({ data }) {

  const customer_id = data['customer-id'];
  const sound_id = data['sound-id'];
  
  return new Promise((resolve, reject) => {
    //get presigned url

    var myBucket = process.env.NODE_APP_BUCKET_NAME;
    var myKey = "sounds/" + customer_id + "/" + sound_id + ".wav"; 
    const signedUrlExpireSeconds = 120;
    try {
      const url = s3.getSignedUrl('getObject', {
        Bucket: myBucket,
        Key: myKey,
        ResponseContentDisposition: 'attachment',
        Expires: signedUrlExpireSeconds
      });
      resolve(url)
    }
    catch {
      console.log('S3 Object does not exist');
      resolve('');
    }
  });
}

如何修改我的 server.js 以满足我的两个需求？
