set 404 custom error

Hi, if i set 404 error with this route (where Errors is the name the controller and show404 the method), i have a php error: Class 'Errors' not found.

Code:

$routes->set404Override(Errors::show404);

if i set error with this route the page 404 work.

Code:

$routes->set404Override(function(){echo view('show404.php');});

Why? Where i wrong?

Thanks for the support.

This line of code worked for me.
$routes->set404Override('App\Controllers\Errors::show404');

Because you need to pass along the namespace also.

What did you Try? What did you Get? What did you Expect?

I did a little bit different ...

Route:

PHP Code:

<?php namespace Config;

// Create a new instance of our RouteCollection class.
$routes = Services::routes();

// Load the system's routing file first, so that the app and ENVIRONMENT
// can override as needed.
if (file_exists(SYSTEMPATH . 'Config/Routes.php'))
{
 require SYSTEMPATH . 'Config/Routes.php';
}

/**
 * --------------------------------------------------------------------
 * Router Setup
 * --------------------------------------------------------------------
 */
$routes->setDefaultNamespace('App\Controllers');
$routes->setDefaultController('Home');
$routes->setDefaultMethod('index');
$routes->setTranslateURIDashes(false);
$routes->set404Override(function()
{
    $header = array (
    'icon' => 'favicon',
    'css' => 'nodata',
    'title' => 'Page not found - wdeda',
    'action' => '/search/allmedia/',
    'placeholder' => 'Search'
    );
    
    echo view('templates/headerr', $header);
    echo view('content/error_404');
    echo view('templates/footerfb');
    });
$routes->setAutoRoute(true);

/**

 */

// We get a performance increase by specifying the default
// route since we don't have to scan directories.
$routes->get('/', 'Home::index');

/**

if (file_exists(APPPATH . 'Config/' . ENVIRONMENT . '/Routes.php'))
