How to set up a custom 404 page for Kohana v3 app

Question

How can I do that? I try to do this for about half an hour, and it gets pretty annoying. You would do it, it would be a simple and easy task to create such a structure. I hope that there may be a simple way that I skipped because I start by not having to select this structure at all if such basic settings are so hard to configure.

This is in my bootstrap.php file, which should do the trick.

if ( ! defined('SUPPRESS_REQUEST'))
{
    /**
     * Execute the main request. A source of the URI can be passed, eg: $_SERVER['PATH_INFO'].
     * If no source is specified, the URI will be automatically detected.
     */ 
    $request = Request::instance();
    try
    {
        // Attempt to execute the response
        $request->execute();
    }
    catch (Exception $e)
    {
        if (Kohana::$environment === Kohana::DEVELOPMENT)
        {
            // Just re-throw the exception
            throw $e;
        }
        echo "ok";
        // Create a 404 response
        $request->status = 404;
        $view = View::factory('error404');
        $request->response = $view->render();
    }

    echo $request->send_headers()->response;
}

But I still get

Fatal error: Uncaught Kohana_Request_Exception [ 0 ]: Unable to find a route to match the URI: test ~ SYSPATH\classes\kohana\request.php [ 674 ] thrown in C:\Xampp\htdocs\system\classes\kohana\request.php on line 674

instead of my custom page 404. And yes, Kohana::$environmentset toKohana::PRODUCTION;

He doesn't even get into the unit echo "ok";. Why did the exception not hit?

bootstrap.php :

/**
* Set the production status
*/
define('IN_PRODUCTION', FALSE);

/**
* Execute the main request. A source of the URI can be passed, eg: $_SERVER['PATH_INFO'].
* If no source is specified, the URI will be automatically detected.
*/
$request = Request::instance();

try
{
    $request->execute();
}
catch (Kohana_Exception404 $e)
{
    $request = Request::factory('error/404')->execute();
}
catch (Kohana_Exception403 $e)
{
    $request = Request::factory('error/403')->execute();
}
catch (ReflectionException $e)
{
    $request = Request::factory('error/404')->execute();
}
catch (Kohana_Request_Exception $e)
{
    $request = Request::factory('error/404')->execute();
}
catch (Exception $e)
{
    if ( ! IN_PRODUCTION )
    {
        throw $e;
    }

    $request = Request::factory('error/500')->execute();
}

echo $request->send_headers()->response;

error.php ":

404 403 ( 500;)

throw new Kohana_Exception404;
