Show a specific route instead of error page (404) - Symfony2

The easiest way is to create this file:

• Symfony 3: /app/Resources/TwigBundle/views/Exception/error404.html.twig
• Symfony 4: /templates/bundles/TwigBundle/Exception/error404.html.twig

... and copy this line into it:

{{ render(controller('App\\Controller\\HomepageController::index')) }}

That's it. This will show the home page with a 404 status code. It only works in prod environment (clear the cache!), since in dev and test Symfony always shows its exception page.
