How to get the requested alias in MODx (Revolution) on page 404?

Question

MODX

Is it possible somehow to get on the 404 page the URL or alias of the requested page and not the resource of the error_page itself?
Needed to display a list of pages that have a similar URL/alias.

Answer 1

When returning a 404 error, the URL does not change.
So $_SERVER['REQUEST_URI']for example
