unable to run workflow "Request a resource action"

Hi,

I'm using vCloud Automation Center 6.0.1.1768706 plugin for vCO. It has workflow "Request a resource action" in Requests folder. I'm trying to destroy the catalog resource. I'm seeing the below messages in logs whenever i execute this workflow.

I selected the destroy resource operation. I don't understand why its getting the "change Lease" request form.  Looks like for any resource action we select its trying to get the 'change lease' request form and failing with below messages in logs. what is the provider i need to set in input here and why its always getting "change lease" request form?

var form = vCACCAFERequestsHelper.getRequestFormForResourceAction(operation);
