Filters not working in CodeIgniter 4

PHP Code:

filter
use Modules\Login\Filters\Auth;
use Modules\Login\Filters\Noauth;

public $aliases = [
"auth"    => Auth::class,
"noauth"    => Noauth::class,
];

Auth
public function before(RequestInterface $request, $arguments = null)
{
    if (!session()->get('isAdminLoggedIn')) {
        return redirect()->to(base_url(route_to('admin')));
    }
}

Route
$routes->get("dashboard", "DashboardController::index", ["filter" => "auth"]); 


---

What is the issue in above code. Filter is not working in CodeIgniter 4. Not working filter auth in dashboard route.

The filter seems correct to me, maybe the problem is in the 'isAdminLoggedIn' session value,. Are you sure it is correctly set?

Yes it is correctly set

try follow format  must implement before and after function

Both functions before and after is already implemented but filters not working.

What does not work? The filter is not applied? Or some error?

I had a lot of trouble figuring out filters, but I see that you have api* rather than what I would have expected api/*

I don't know if that matters, but it might.

I am using filters in a custom namespace and that is working fine in all version of CI 4 that I have tried.
