Impossible to use Twig Reference from Symfony in override default error template

I overide custom 404 page by creating structuretemplates/bundles/TwigBundle/Exception/error404.html.twig

Like was told here.

But Twig Reference from Symfony not working there. I tried path(), url() and tag trans

Standard twig functions like min() work coretly. I use Symfony 4.4.5

How can I use them in that template??
