Cause You might still be using UI15 and not UI16 The UI16 plugin is not active. There is a dependency for Service Mapping home page with UI16. Resolution Activate plugin : "com.glide.ui.ui16" If this is a non-production instance, with admin role you should be able to activate it yourself from the plugin list. If this is production, you will have to put in a HI request to have that plugin activated. Additional Information Activating this plugin automatically forces all end-users with exception to admin users to use the new UI. If you need to prevent this you will have to create a property and set it to 'public'. This will not prevent end-users from not getting the new UI, but it will give them the option to switch back to UI15. See here for more details on the property: https://docs.servicenow.com/csh?topicname=t_SwitchBtwnUi16AndUi15.html&version=latest#t_SwitchBtwnUi16AndUi15
