Hi @vkarpov15 ✋

This test seems flaky:

mongoose/test/errors.validation.test.js

Lines 235 to 249 in d909525

	describe('when user code defines a r/o Error#toJSON', function() {
	it('should not fail', function(done) {
	const err = [];
	const child = require('child_process')
	.fork('./test/isolated/project-has-error.toJSON.js', ['--no-warnings'], { silent: true });
	child.stderr.on('data', function(buf) { err.push(buf); });
	child.on('exit', function(code) {
	const stderr = err.filter(line => !line.includes('Warning: ')).join('');
	assert.equal(stderr, '');
	assert.equal(code, 0);
	done();
	});
	});
	});

It failed in my last two PRs with a timeout error on this environment Node 16 MongoDB 5.0.11 OS ubuntu-20.04
I'm not able to reproduce it and tests are passing locally.

Any suggestions on how to fix the problem or reproduce the problem locally?
I've tried using this package to trigger actions locally with no luck.
Maybe I should open a related issue?

@lpizzinidev I'd first suggest increasing the test's timeout using this.timeout(10000). It may just be that the test is slow because it spawns a new process.
