Use vco to update vcac inventory

Hi,

Is there someway in vco to force vcac to take an inventory?

At the moment I have a vco workflow which deploys to vsphere ok,  then I run the inventory task manually followed by 'Import vCenter Virtual Machine'. This works well and puts the machine in vcac.

I'd like to automate the whole thing, I have tried using 'Register a vcenter virtual machine' but this leads to errors in the log, Workflow "RegisterVirtualMachineRequest" failed with the following exception: Object reference not set to an instance of an object. So I'm guessing that is not the way to go.

I should add I can use 'force data collection', but it would be nice to focus on only the new vm.

Cheers
