codeigniter_4 the redirection method is not working

Question

    public function isAuth($page,$data){
        $session = \Config\Services::session();
        if(empty($session->get(SES_ADMIN_USER_ID))){
            return redirect()->route('admin/login');
        }else{
            $this->load_page($page,$data);
        }
    }

when the sessionis not set the code is going in the if condition but this redirection is not working

return redirect()->('admin/login');

this is muy route

$routes->get('/admin/login', 'Admin\Admin_Controller::load_login');

i tried other redirection methods but they are not working

Answer 1

What you're looking for is: return redirect()->to('admin/login');
