Custom Error Page Configuration for On-Premises Deployment

Hi, Developers   Do you have a good idea of how to configure a custom error page for on-premises deployment? explains it for cloud deployment, but it doesn't seem to work for on-premises deployment and local testing.   I tried to find some runtime configuration for it, but I couldn't. It could be done by WAS for reverse proxy configuration, but what I want it without separated WAS.   I appreciate any help from you.
