How do I manually initiate the 404 handler in Slim 3?

Question

We already know how to add a custom 404 notFoundHandler in Slim 3:

$container['notFoundHandler'] = function ($c) {
    return function ($request, $response) use ($c) {
        return $c->view->render($response, 'pages/404.html.twig') 
            ->withStatus(404)
            ->withHeader('Content-Type', 'text/html');
    };
};

I would like to trigger this manually in one of my routes.

In Slim 2, we were able to do something like $app->notFound(). What is the equivalent in Slim 3?

You need to throw a new instance of \Slim\Exception\NotFoundException

throw new \Slim\Exception\NotFoundException($request, $response);

I found this answer on Google, so i'm commenting for new users. For Slim 4, use HttpNotFoundException, like: `throw new \Slim\Exception\HttpNotFoundException($request, "Resource not found")` – Bruno Pitteli Gonçalves Jan 04 '21 at 16:49
How do you use the second argument? Say to display it on the error page. – Fabien Snauwaert Jan 19 '21 at 10:21
