Redirecting with the Location header

I was stuck with a redirection not happening in a Nuxt middleware on a recent project:

export default defineNuxtRouteMiddleware((from, to) => {
  const { isLoggedIn } = useAuth();

  if (!isLoggedIn()) {
    return navigateTo('/login', {
      redirectCode: 401,
    });
  }
});

When trying to access a page without being logged in, instead of being redirected, the browser was displaying a message "Redirecting to /login". It turns out that using the 401 (unauthorized)status code was blocking the redirection specified in the response Location header. The documentation on MDN is quite clear on the subject:

The Location response header indicates the URL to redirect a page to. It only provides a meaning when served with a 3xx (redirection) or 201 (created) status response.

Changing the redirectCode value from 401 to 302 (found) fixed the issue:

  export default defineNuxtRouteMiddleware((from, to) => {
    const { isLoggedIn } = useAuth();

    if (!isLoggedIn()) {
      return navigateTo('/login', {
-       redirectCode: 401,
+       redirectCode: 302,
      });
    }
  });

Although, I am not sure if this is the correct status code for an authentication middleware.
