[keycloak-user] Custom page for not found realm (tenant)

Hi, We are using KeyCloak with multi-tenancy, each realm represents a tenant (customer). Sometimes due to setup issue or typo in the realm name we are getting 404 page, is there a custom page or a way to customize a page for missing realm scenario ? For example something like - Realm <name> doesn't exist... Thanks, Haim. The information contained in this message is proprietary to the sender, protected from disclosure, and may be privileged.
