Requests don't work consistently with MSW

[charklewis]

I am trying to set up a MSW to test my app and I have found that when I use the request method from this SDK the requests haphazardly fail. I have been tracking this issue on MSW's repo as I thought it was a bug there. You can see that issue here - mswjs/msw#1143.

I have created a small repo you can use to reproduce the error. Are you able to advice if there are changes I need to make to the configuration in order to get these tests to pass? If you swap out the client.request method for the typical fetch you will see the pass without issues.

I have confirmed the issue does not persist when I use cross-fetch or node-fetch. It only occurs when I use client.request or request from graphql-request.

Do you experience the same behavior if you disable MSW in your tests?

I think this still may be an issue with how MSW handles the request instance created by graphql-request (we've had a bunch of examples when third-party tools construct requests in a rather non-standard way; some were handled, others were concluded to be against the spec). I'd say so far the source of the issue remains ambiguous.

I attempted this today and the tests work if I use the real server and don't mock the response. So the errors only appear when using MSW.
