Unable to intercept octokit request using msw v2.

[Lord-Kamina]

Prerequisites

• I confirm my issue is not in the opened issues
• I confirm the Frequently Asked Questions didn't contain the answer to my issue

Environment check

• I'm using the latest msw version
• I'm using Node.js version 18 or higher

Node.js version

20.18.1

Reproduction repository

https://github.com/Lord-Kamina/always-upload-cache/tree/msw-issue

Reproduction steps

npm run test -- --runInBand --verbose --testLocationInResults=true --runTestsByPath tests/saveImpl.test.ts

Current behavior

The 'DELETE' requests sent by octokit are not being intercepted by MSW

Expected behavior

They should be intercepted? I really don't know what am I doing wrong.
What was virtually the same code was working in node16 using msw 0.49, you can see the working branch here: https://github.com/Lord-Kamina/always-upload-cache/tree/allow-refresh

Some more info... from this https://github.com/octokit/action.js/blob/49a9baa814345814970d410d61f5880a35e2cdf9/src/index.ts#L9, I gather this is related to #2165, but I didn't really understand how to fix it from what was described in that issue.

@Lord-Kamina, thanks for opening this. Since Oktokit makes requests via unidici directly, those requests are not visible to MSW. We currently only support ClientRequest, XHR, and global fetch. Undici's request is a custom request implementation on top of net, which isn't supported by MSW at the moment.

We've done some preliminary work in https://github.com/mswjs/interceptors/releases/tag/v0.32.0, which now technically allows us to intercept raw net.Socket connections in Node.js. We still need to implement the actual interceptor, think how to reuse it in the ClientRequestInterceptor, and the publish it.

I've outlined the official proposal for this in mswjs/interceptors#707. I doubt I will find the time for it this year, but it always welcomes a thorough discussion first. I would be grateful for your input on it, if you have any. Thanks.
