cy.intercept not breaking if request object is wrong

Hello,

I want to test that an outgoing request has the correct body. I saw in the documentation that you can do it like this.

describe('Check Marketing logging', () => {
	before(function () {
		cy.visit('https://www.independer.nl/zorgverzekering/intro.aspx');
	});

	it('Check button click - intercept req', function () {
		const requestBody = { "wrong": "request body" };

		cy.intercept('POST', '/api/ue/c', (req) => {
			expect(JSON.stringify(req.body)).to.include(JSON.stringify(requestBody));
		}).as('sLIdentifier');

		cy.getByUe('man', 'input').click({ force: true });

		cy.wait('@sLIdentifier');
	});
});

The only thing is if the condition is right or wrong the runner always shows succeded. See image below.

It feels like this is a bug. The workarround I have now it doing it on the wait like this.

it('Check button click - intercept wait', function () {
	const requestBody = { "wrong": "request body" };

	cy.intercept('POST', '/api/ue/c').as('sLIdentifier');
	cy.getByUe('vrouw', 'input').click({ force: true });
	cy.wait('@sLIdentifier').should(({ request }) => {
		expect(JSON.stringify(request.body)).to.include(JSON.stringify(requestBody));
	})
});

Ah I found the issue. We are using a Cypress Helper package with custom function etc. But in there this code was placed

Cypress.on('uncaught:exception', (err, runnable) => {
	// returning false here prevents Cypress from
	// failing the test
	return false;
});

So when I removed this code it works fine. Don’t know why we put this code here the first place 😦

Thanks for the help.

I cannot recreate this problem with Cypress v6.3.0 using https://github.com/cypress-io/cypress-test-tiny/tree/intercept-issue-14671
