Cannot find Array.Object Data Capsule to drag and drop in Flow Designer

[GaneshKumar]

Greetings All,

I am trying to perform a POC for Coupa Spoke via Flow Designer

The goal was to create requisition in Coupa from servicenow PO (wireless mouse) from proc_po / proc_po_item tables

Servicenow PO triggers >> Coupa Create requisition

However when attempting to create the follow, i am not getting the option to select the inputs in Requisition lines

When tried to dot walk, all the fields were grayed out.

To the right, i cannot see a data capsule with Array.object type

Please advise, what could i be missing, Thank you in advance !
