Microsoft Azure Runbook不执行PowerShell脚本

我试图在Micrososft Azure Runbook中运行下面的powershell脚本。 但是，我不断收到错误：

脚本如下：

#### Provide the computer name in $computername variable $ServerName = "testauto","LocalHost","Server-2","Not-Exists", "Fake-computer", "Dc-1" ##### Script Starts Here ###### foreach ($Server in $ServerName) { if (test-Connection -ComputerName $Server -Count 2 -Quiet ) { write-Host "$Server is alive and Pinging " -ForegroundColor Green } else { Write-Warning "$Server seems dead not pinging" } } 

该脚本在Powershell ISE中运行正常，但不在Microsoft Azure自动化Runbook中运行。

有人可以让我知道为什么吗？

干杯
