vRA/vRO 7 - Get the custom properties values

I am trying to update the VM hostname and created a few property definition and added them into the property group.

Within the property group, I have created:

• Extensibility.Lifecycle.Properties.VMPSMasterWorkflow32.BuildingMachine
• Extensibility.Lifecycle.Properties.VMPSMasterWorkflow32.Request

Both have the values __*,*

The property group is added to the blueprint and I have also created the new Event Subscriptions with the following setup:

• Select "Machine Provisioning" topic
• Added the following conditions
  • Data > Lifecycle state name EQUALS VMPSMasterWorkflow32.BuildingMachine
  • Data > Lifecycle state phase EQUALS PRE
  • Data > Machine > Machine Type EQUALS Virtual Machine

In the vRO workflow scripting, I am passing the "Payload" as Properties into the workflow

I am able to retrieve the machine ID

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

machineId = machine.get("Id"); // Value is returned

var machineProperties = machine.get('properties'); // Getting NULL when retrieving the properties

The machineProperties is returning NULL and I am not able to proceed further to retrieve the property definition that I have specified.

Am I missing anything? Please help! Thanks.
