Problems Running Azure Automation Powershell to Scale Database Back After Restore Operation

I am trying to scale back a database after the restore operation has completed and am running into some problems. I am getting this exception and wonder if there is something in this script not supported by Azure Automation Workflows?

Parameter set cannot be resolved using the specified named parameters.

  <#  
  .SYNOPSIS   

The purpose of this runbook is to demonstrate how to restore a particular database to a new database using an Azure Automation workflow. Then it is scaled back to Basic.
