For some reason my 404 page is not working. The error is:
Error: An exception has been thrown during the rendering of a template ("Trying to get property 'title' of non-object").: Page not found

I haven't seen this error before and I don't know where to set the "title" of a 404 page as it's not actually a page. I assume because it's asking for an object that this could be a PHP error not a Twig or YAML?
