OOTB - Destroy A Computer

As part of my retirement process, I want to remove the VM from AD. I created a WF with a scriptable task in which I pass the VM name and convert it to an AD:ComputerAD object and attempt to pass that variable to the OOTB Destroy a Computer WF.

The script is pretty simple.

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

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

var vm = machine.get("name");

computer = ActiveDirectory.getComputerADRecursively(vm);

System.log("Computer count: "+computer.length);

for each (pc in computer){

System.log("Checking computer: "+pc.name);

    if (vm.toLowerCase() == pc.name.toLowerCase()){

    System.log("Found Computer: "+pc.name);

    }

}

When the WF is executed I end up with a Bad Syntax 'Array" error.
