Extensibility Script missing information

I did an inplace upgrade of vRO to 7.3.  Prior to that I was able to pull information from extensibility and use it on my customization scripts. However since the upgrade many values are now returning NULL.

Working Script pre-vRO 7.3:

var executionContext = System.getContext();

System.log("BlueprintName: " + payload.get("blueprintName")) ;

System.log("ComponentId: " + payload.get("componentId")) ;

System.log("ComponentTypeId: " + payload.get("componentTypeId")) ;

System.log("EndpointId: " + payload.get("endpointId")) ;

System.log("RequestId: " + payload.get("requestId")) ;

System.log("VirtualMachineEvent: " + payload.get("virtualMachineEvent")) ;

System.log("WorkflowNextState: " + payload.get("workflowNextState")) ;

var lifecycleState = payload.get("lifecycleState") ;

System.log("State: " + lifecycleState.get("state")) ;

System.log("Phase: " + lifecycleState.get("phase")) ;

System.log("Event: " + lifecycleState.get("event")) ;

var machine = payload.get("machine") ;

System.log("ID: " + machine.get("id")) ;

System.log("Name: " + machine.get("name")) ;

System.log("ExternalReference: " + machine.get("externalReference")) ;

System.log("Owner: " + machine.get("owner")) ;

System.log("Type: " + machine.get("type")) ;

System.log("Properties: " + machine.get("properties")) ;

var vCACVmProperties = machine.get("properties") ;

if (vCACVmProperties != null) {

  var log = "";

  log += "vCAC VM properties :\n";

  var array = new Array();

Now, that script returns the following:

workflow: 'Adding the server DNS' (d30146ed-b02f-4818-8340-b55409a57485)

Some of the information comes back normally while others return a null value, including the IP address.  When I look in vCenter the VM shows the IP correctly.  Has anyone seen this?  Any workarounds?

Thanks
