redirect_uri_missmatch cant figure out what is wrong with url

I am trying to create an automated login in Cypress.
I already followed the tutorial in the docs; from this, I can retrieve the user and its information.
The problem is that my API uses its own JWT, which I am trying to follow to log in. When I reach the same endpoint as the visual Google SSO callback does, I provide the authorization code hoping to be able to log in, but I keep getting `redirect_uri_missmatch` and not much more information in the `getToken` method.

```

As far as I know, I need to insert in the console the URL that is making the POST, which I did. Also, I know that from the visual login I get the current URL, so I can add it in the console, but not that much from this.

And this starts with a GET from localhost:3000/pas/auth/callback?, so I believe I am missing a small thing here

So far I have localhost:3000 and localhost:3000/pas/auth/callback in the allow list
