ASD - Change Item (machine) Lease through VCO Workflow

Anybody have success in 6.1.x they would be willing to share?

There seems to be potentially a REST mechanism to do so by adding VCAC as a REST endpoint to VCO. That is less than ideal.

Would rather perform the action through the IaaS VCACCafe interface  (which is itself REST it appears, but nonetheless... the APIs are defined).  There seems to be a break on the ability to execute Resource Actions from a workflow at all.  Methods that used to be defined no longer work.

// should return Array of vCACCAFECsResourceOperation, but doesn't work = "403 forbidden"... it is the wrong return type anyway

var errorForbidden = vCACCAFEEntitiesFinder.getResourceActions(cafehost);

Any ideas?
