Intercept not working properly

[B34v0n]

I'm trying to test my Angular app in the component-testing-mode.
In there, I've got a component with a service with 2 requests.
One of them can be intercepted, the other one can't, and I cannot figure out, why.

So here are the details:
In the service, there are the following two HTTP-Request:
this.http.post<Type>(url + '/catalog', body, { headers });
and
this.http.get<Type>(url + '/measure/' + id);
(The Type is the same)

The Interceptors look like this:
cy.intercept({ method: 'POST', url: '**/catalog' }, [returnValue]).as('getCatalog');
and
cy.intercept({ method: 'GET', url: '**/measure/**' }, [returnValue]).as('getMeasure');

The Post-Interceptor works like a charm and always returns the returnValue.
BUT the Get-Interceptor doesn't work at all. Cypress says, the interceptor was never called, but at the end of the test also says, that there is a HTTP-Request, that returned 404. But said request is .../url/measure/1. I even tried to copy the complete url, but that also didn't work.

Anybody got an idea, what the problem could be? I'm desperate.

If anyone has the same error and is desperate as I was, I had a stupid error.
My URL started without a slash.
The requests were send to the cypress-own-backend.
So the post-Request was mocked, because there was no post in the cypress-backend, but the get-Request wasn't mocked, because cypress tried to get something from this backend.

so instead of const url = 'this/is/my/url' I just needed to write const url = '/this/is/my/url'

Thank you for the hint. But there is still a problem when an app actually fetches url without slash (e.g. fetch(".auth/me")) - Cypress can't intercept it, returning the internal source code.
