JS and CSS URL change

Hello,

I have a problem with a methohe from a controller. Indeed, when I call it the js and css loading path changes and they fail to load.

correct path : http://localhost:8081/assets/images/logo.svg
wrong path after method call : http://localhost:8081/update_user/assets...s/logo.svg
Below my code 

PHP Code:

$routes->get('/users', 'Admin/Users::index');
$routes->get('/add_user', 'Admin/Users::add_user');
$routes->get('update_user/(:num)', 'Admin/Users::update_user/'); 


PHP Code:

public function update_user($id)
    {
 if($this->request->getMethod() == 'get'){ 
 if (session()->get('login') != "") {

                $userModel = new UserModel();
                $user = $userModel->find($id);

                $profilModel = new ProfilModel();
                $profilsItems = $profilModel->findAll();

                $data = [
                    'title_meta' => view('partials/title-meta', ['title' => 'Utilisateurs']),
                    'page_title' => view('partials/page-title', ['title' => 'UpdateUser', 'pagetitle' => 'GestionUtilisateurs', 'link' => 'users']),
                    'user' => $user, 
                    'profils' => $profilsItems
                ];
    
                return view('admin/edit_user_2', $data);
            } else {
                return redirect()->to('/login');
            }
 }

        if($this->request->getMethod() == 'post'){
            // ---- store details in database
 $model = new UserModel();

 $updateData = [
 'nom' => $this->request->getVar('nom'),
 'prenom' => $this->request->getVar('prenom'),
 'email' => $this->request->getVar('email'),
 'mobile' => $this->request->getVar('mobile'),
                'tel' => $this->request->getVar('tel'),
                'id_profil' => $this->request->getVar('id_profil')
 ];

            $model->where('id', $id)
 ->set($updateData)
 ->update();

 return redirect()->to('/users');
        }
    }






Thanks for your help !
