Description

• Powershell scripts that work directly on the machine may produce the following output:

' out-lineoutput : The handle is invalid. + CategoryInfo : NotSpecified: (:) [out-lineoutput], IOException + FullyQualifiedErrorId : System.IO.IOException,Microsoft.PowerShell.Commands.OutLineOutputCommand'

Environment

• N-able N-central

Solution

• This error started to appear in Windows 10 builds after 1903 when using the "Run PowerShell Script" object
• Any code involving creating something on the device needs to be wrapped to a variable.
• Example:

New-Item -ItemType Directory -Path $Folder

• Use Instead:

$resultInfo = New-Item -ItemType Directory -Path $Folder -Force

• Development has also indicated you can downgrade powershell to version 5.1.17763 or upgrade to version 6.0 or 7.0 and this error will not show.
