Virtual Machine Manager Error ID 23351 FirstBootDevice Invalid

When moving, importing, exporting Generation 2 template in VMM, the following error occurs when trying to deploy :

The input string "
" for the FirstBootDevice parameter cannot be parsed and may be invalid.
Make sure the string uses one of the following formats: "SCSI,BusId(integer),LunId(integer)" or "NIC,SlotId(integer)"
ID: 23351

Here’s a quick Fix:

Set-SCVMTemplate -Name 'TEMPLATENAME' -FirstBootDevice 'SCSI,0,0'

Better yet, it’s advisable to include the cmdlet above into the importing function of VM templates. A Try-Catch clause with error 23351 keyword could be coded to handle these exceptions during VM provisioning automations.
