Error: InvalidOperation RuntimeException UsingWithoutInvokeCommand

[WayneSherman]

Using file \Scripts\Invoke-CommandAs.ps1 downloaded from github. Testing on Windows 10 IoT Enterprise LTSC 2019 (ver 1809)

test.ps1 has 2 lines:

. $PSScriptRoot\Invoke-CommandAs.ps1
Invoke-CommandAs -ScriptBlock { Get-Process } -AsSystem

When running I get several error messages, the first one is:

A Using variable cannot be retrieved. A Using variable can be used only with Invoke-Command, Start-Job, or InlineScript in the script workflow. When it is used with Invoke-Command, the Using variable is valid only if the script block is invoked on a remote computer. At C:\util\Invoke-CommandAs.ps1:555 char:21

• ... $Using:Function | ForEach-Object { Invoke-Expression $ ...

• 
  + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
  + FullyQualifiedErrorId : UsingWithoutInvokeCommand

Seems the issue is when you're not using the Invoke-CommandAs on a remote machine (ie: you're running it locally).

[WayneSherman]

Correct. For my use case I need a simple way to execute PowerShell commands and scripts as "NT AUTHORITY\SYSTEM" on the local computer.

You can use the Invoke-ScheduledTask function in the private folder to run it locally. That’s what I’ll be doing in the next version. If no ComputerName/Session provided, run it directly as a ScheduleTask.

Thanks, Invoke-ScheduledTask is working.

3.1.4 has been publish to the gallery. This should work now with Invoke-CommandAs locally.
