cy.route2 routes not being matched with external URLs

First of all, thanks for the work on cy.route2, it looks like it’s going to make a lot of things much easier to do! I’ve jumped in to try it out and am having some trouble with URLs that are outside of my application (ie, API requests and such).

Current behavior:

If the application sends a request to an external URL:

fetch('https://example.cypress.io/example-path')

In the tests, when cy.route2 is used, it does not appear to be possible to match the request.

Specifying path:

cy.route2({ path: '/example-path', method: 'GET' }, { fixture: 'example.json' }).as('example');

Specifying url:

cy.route2({ url: 'https://example.cypress.io/example-path', method: 'GET' }, { fixture: 'example.json' }).as('example');

Specifying hostname:

cy.route2({ hostname: 'example.cypress.io', method: 'GET' }, { fixture: 'example.json' }).as('example');

Specifying hostname and path:

cy.route2({ hostname: 'example.cypress.io', path: '/example-path', method: 'GET' }, { fixture: 'example.json' }).as('example');

Desired behavior:

The request should be matched by the routes, and stubbed accordingly.

I am also seeing this behavior in the new 5.2.0 version.

I’ve narrowed down the issue and it seems to only affect HTTPS traffic to a different origin, opened a PR to fix: https://github.com/cypress-io/cypress/pull/8662
