vCO 5.5.2 and vCAC 6.1 plugin REST API Error

Hello,

I'm getting an error when trying to make calls from vCO 5.5.2 to the vCAC 6.1 REST API requesting catalog items.  This same code works fine with the vCAC 6.0.1 plugin.

Error:

Data serialization error. (Workflow:Test vCAC Rest / Scriptable task (item1)#24)

Code:

var item = {"@type": "CatalogItemRequest",

"catalogItemRef": {"id": "3e6c3f13-6ea0-4da5-8bac-d8cb27e64f24"},

"organization": {"tenantRef": "vcacadmin",

var catalogRest = vcac.createRestClient(vCACCAFEServicesEnum.CATALOG_SERVICE);

var response = catalogRest.post("consumer/requests",item);
