Jest returns "Network Error" when doing a mock request with axios and msw

I have been using msw and axios to test my APIs in front end (node-typescript). The APIs return valid responses when I access them through Postman. The jest test for testing the GET API is

server = setupServer(...mocks)

server.use(
  
  rest.get(sampleUrl, (req, res, cx) => {
    return res.once(sampleResponse)})
);

server.printHandlers(); // on printing handlers, I see the sampleUrl printed

const features = await sampleMethod(param1);

expect(features).toEqual(sampleResponse);

On executing the above(only for a particular API) I seem to get this error

[MSW] Error: captured a request without a matching request handler:

  • GET sampleUrl

If you still wish to intercept this unhandled request, please create a request handler for it.

The full exception is:

}

When I use a different API, the test works as expected.The test fails only for a particular GET API.
