Question

I’m trying to use more than one function in my Azure Function, but while the first one created works normally (returns me a Status 200), the second one always returns a 401 error, it is a code that must accept one JSON and return another JSON. I’ve already enabled and disabled CORS, changed the AuthLevel to Anonymous, and among other things, but it always returns me this 401 error. I created a third test function, and it also returns the 401 error. Its code is nothing more than the “Hello World” of the Azure Function, there’s nothing special about it.

Has this ever happened to anyone? Do you know what it could be?

enter image description here

I don’t know if this is relevant, but when trying to run the second or third function locally, this error is returned to me. However, he cites the first code, which works:

I tried changing the permissions for Function, Anonymous and Admin and none of them worked. I also enabled CORS.
