UI Page in Self service PortalSummaryWhy UI Pages are not available in Self-service Portal? The Service Portal runs on Angular v1.5.11, and UI Pages use Rhino Javascript and Apache Jelly. These are not compatible languages, meaning unfortunately you'll have to recreate the UI Page as a Service Portal widget for it to work on the Service Portal As a workaround, you could use a Macro variable in your Service Catalog Item, and that way you can create a UI Macro and Service Portal widget so that you can have it available to you on the platform site and the Service Portal.https://community.servicenow.com/community?id=community_question&sys_id=7b8190badb023b402e8c2183ca961972
