solution

use node-fetch instead of Node.js undici fetch ❓

$ npm i node-fetch
$ npm i -D @types/node-fetch

https://www.npmjs.com/package/node-fetch

import fetch from 'node-fetch';

// fetch-polyfill.js
import fetch, {
  Blob,
  blobFrom,
  blobFromSync,
  File,
  fileFrom,
  fileFromSync,
  FormData,
  Headers,
  Request,
  Response,
} from 'node-fetch'

if (!globalThis.fetch) {
  globalThis.fetch = fetch
  globalThis.Headers = Headers
  globalThis.Request = Request
  globalThis.Response = Response
}

// index.js
import './fetch-polyfill'

// ...

arrayBuffer & res.clone()

import fetch from 'node-fetch';
const response = await fetch('https://example.com', {
  // About 1MB
  highWaterMark: 1024 * 1024
});

const result = await res.clone().arrayBuffer();
console.dir(result);

demos

  async fetchVideo(url, filepath) {
    const filename = `${filepath}.mp4`;
    return fetch(url)
      // .then((res) => res.arrayBuffer())
      .then((res) => {
        console.log(`loading ... ⏳`);
        return res.arrayBuffer();
      })
      .then((buffer) => {
        console.log(`finished ✅`)
        let arrayBuffer = Buffer.from(buffer)
        fs.writeFile(filename, arrayBuffer, (err) => {
          if (err) {
            console.error(err);
            console.error(`❌ video url`, url);
          } else {
            console.log("video downloaded successfully");
          }
        });
      })
      .catch((err) => console.error(`❌❌ video url`, url, err));

Fetch API

https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API

Instance methods

arrayBuffer()
blob()
clone()
formData()
json()
text()

Response.clone() Creates a clone of a Response object.

https://developer.mozilla.org/en-US/docs/Web/API/Response/clone

The arrayBuffer() method of the Response interface takes a Response stream and reads it to completion.
It returns a promise that resolves with an ArrayBuffer.
