What happened?

I am unable to see nock debug logs, and I've tried everything recommended by the docs. I've used every env var combination of {DEBUG, NODE_DEBUG} and values {nock, nock.*}.

I use debug-logging of my own on this machine plenty and it works fine, but it stopped working recently for nock. Perhaps caused by your removal of debug in favor of node's built-in debuglog?

In theory I could switch back to non-beta nock, but the beta's are the only ones that work with fetch() (including streams and buffers and other little details) for me.

Here's my test.js file:

const nock = require('nock');

describe('suite', () => {
	afterEach(async () => {
		nock.cleanAll();
		nock.enableNetConnect();
	});

	it('test', async () => {
		const scope1 = nock('https://www.google.com')
			.persist()
			.post('/')
			.reply((uri) => {
				return [200, 'nock fake result'];
			});

		const response = await fetch('https://www.google.com', { method: 'POST' });
		const result = await response.text();
		console.log('received:', result);

		scope1.done();
	});
});

Here's the result in the terminal:

 DEBUG=nock node ./node_modules/mocha/bin/mocha test.js

  suite
received: nock fake result
    ✔ test


  1 passing (20ms)

~/nock_probs ❯❯❯ DEBUG=nock.* node ./node_modules/mocha/bin/mocha test.js


  suite
received: nock fake result
    ✔ test


  1 passing (18ms)

~/nock_probs ❯❯❯ NODE_DEBUG=nock.* node ./node_modules/mocha/bin/mocha test.js


  suite
received: nock fake result
    ✔ test


  1 passing (18ms)

~/nock_probs ❯❯❯ NODE_DEBUG=nock node ./node_modules/mocha/bin/mocha test.js 


  suite
received: nock fake result
    ✔ test


  1 passing (18ms)

In case you need it, here's the package.json:

{
  "dependencies": {
    "mocha": "^10.4.0",
    "nock": "^14.0.0-beta.5"
  },
  "engines": {
    "node": "18.20.2"
  },
  "volta": {
    "node": "18.20.2"
  }
}

Embarassingly, the issue was I was using "NODE_DEBUG=nock." instead of "NODE_DEBUG=nock:". Make sure to use a colon, not a period.
