ICF node for Service 'PAGE_BUILDER_CONF', Namespace '/UI2/' not available under node 'odata'

Hello Experts,

I am trying to configure Fiori Launchpad in my gateway system, While launching url  <server>:<host>/sap/bc/ui5_ui5/sap/arsrvc_upb_admn/main.html

I am getting error "ICF node for Service 'PAGE_BUILDER_CONF', Namespace '/UI2/' not available under node 'odata'"

I can see that in /IWFND/MAINT_SERVICE, the status of SICF node for service PAGE_BUILDER_CONF is grayed out.

While try activating the same, I also get same error.

Please help.

Regards,

Anurag.
