'TypeError [ERR_INVALID_ARG_TYPE]: The "target" argument must be an instance of Buffer or Uint8Array. Received null' : React Testing library using msw

Question

When I run a test code using React testing library with MSW, I got an error

buffer.js:210
throw new ERR_INVALID_ARG_TYPE('target', ['Buffer', 'Uint8Array'], target);
^

There are 6 test functions in a Component.test.tsx file and all functions have similar code like

test('some test..', async () => {
  server.use(
    rest.get('/api/1/..', (req, res, ctx) => {
      return res(ctx.json({...}));
    }),

    rest.get('/api/2/..', (req, res, ctx) => {
      return res(ctx.json({...}));
    }),
  );

  render(<Component />);
  await waitFor(() => screen.getByText(/test test/i));

});

above.

The bigger problem is sometimes the test passes, even though most time it fails.

I tried dividing each test function in a different test file, like component1.test.tsx, component2.test.tsx, ... component6.test.tsx.

And the result was really weird because Jest pass whole files.

I really want to know why the error is happening.
