What I am trying to do is redirecting users to a custom page, instead of showing the standard error message, when a 403 or 404 error happens.
I tried to use /error/404 on the Base site settings page and create a node with that path alias, but it didn’t work. When I try to access some random URL, it still shows a standard error message, not the /error/404 node.
Did I misunderstand how the feature work? Should I try another approach?
