TypeError: Cannot redefine property: Request at Function.defineProperty (<anonymous>)

Okay after dealing with TextEncoder and ReadableStream is not defined errors, I finally got chance to test my api but now
I'm getting this error when I run my test on my reservation.test.tsx file.

TypeError: Cannot redefine property: Request
    at Function.defineProperty (<anonymous>)

   9 | import { server } from './__tests__/__mocks__/msw/server';

     |                        ^
  12 | afterEach(() => server.resetHandlers());
  13 | afterAll(() => server.close());

https://github.com/halilibrahimcelik/jest-test-repo-base-venue this is the project repo btw, you can look at my configurations on msw handlers and servers file as well as jest files.

Any help really appreciated.

When I look at Discussed in #2271, I thought the problem might related to version, so I changed it from 2.4.8 to 2.4.7 as described but my problem was still there. So after further research, I saw this comment #2271 (comment) and finally 2.4.3 version solved my problem.
I also configured my setupfile like this

  const { TextDecoder, TextEncoder } = require('node:util');
const { ReadableStream } = require('node:stream/web');
Object.defineProperties(globalThis, {
TextDecoder: { value: TextDecoder },
TextEncoder: { value: TextEncoder },
ReadableStream: { value: ReadableStream },
});

const { Blob, File } = require('node:buffer');
const { fetch, Headers, FormData, Request, Response } = require('undici');

Object.defineProperties(globalThis, {
fetch: { value: fetch, writable: true },
 Blob: { value: Blob },
File: { value: File },
Headers: { value: Headers },
FormData: { value: FormData },
 Request: { value: Request },
Response: { value: Response },
});

I ran in the same issue and switched to this setup and removed undici completely:
#1916 (comment)
and with this switch the error is gone

this solved my issue. Hopefully this gets fixed in the future versions
