Cannot access response body after request is intercepted by MSW

Environment

Name	Version
msw	0.35.0
chrome	Version 91.0.4472.114
Ubuntu	20.04.2 LTS

Request handlers

I have the following setup for msw in my project. The request that I’m having an error should be bypassed.

const setup = () => {
  if (typeof window === 'undefined') {
    const { server } = require('./server');
    server.listen();
  } else {
    const { worker } = require('./browser');
    worker.start({ onUnhandledRequest: 'bypass' });
  }
};

Actual request

const parseJSON = (text) => JSON.parse(text);

fetch('/url').then((res) => parseJSON(res.text()))

Current behavior

I get the following error in my application

Uncaught (in promise) TypeError: Failed to execute 'text' on 'Response': body stream already read
    at parseJSON

Expected behavior

I should be able to access the response.text in the promise resolve as the request was bypassed.

No. Cloning the repo and manually bumping mswjs/interceptors to the current version worked for me. I need to get a little organized, but I can have a PR ready this week.

Hey, @romaolucas.

We’ve fixed this issue in the browser about half a year ago. What you’re experiencing is likely to be a Node.js issue that was raised in the related library and fixed (https://github.com/mswjs/interceptors/releases/tag/v0.12.7). Please wait for the next MSW release for the fix to land in your project. Thank you!
