    I have same problem.

    In slim3, NotFoundException are throwed (and capture by "notFoundHandler") when no matching route was found.

    But if a route is found, (ie "/user/toto" for pattern "/user/{toto}") how to throw a NotFoundException if "toto" is not a user ?

    I respond to myself : "middleware is magic"

    I just add a middleware :

    $app->add(function ($request, $response, $next) {
        try {
            $response = $next($request, $response);
        catch(Slim\Exception\NotFoundException $e) {
            $notFoundHandler = $this->get('notFoundHandler');
            return $notFoundHandler($request->withAttribute('message', $e->getMessage()), $response);
        return $response;

    And now, anywhere in my app, i can throw a NotFoundException :

    throw new NotFoundException("Product not found");
