Filter criteria 'q' of Call REST Endpoint from a Business Object not working.
I trying to use the filter 'q' on the Call REST Endpoint and it doesn't work with a variable of string.
If I set as a Static Content like: ('businessUnit=AMMO_BU') it works
Also works with a integer variable like: ('transactionNumber=' + $page.variables.transactionNumberVar)
But if I try to do ('businessUnit=' + $page.variables.businessUnitVar) it doesn't work and I get an error (Error response during RestAction).
