Action Run Powershell Script Fail

Posted on by lkjio

Hello,

Need someone advise on this. Run out of solutions. I have a simple Run PowerShell Script with the same code as the Microsoft documentation: https://docs.microsoft.com/en-us/power-automate/desktop-flows/actions-reference/scripting

It fails every time I run the flow. The thing is the flow was already running Run PowerShell Script actions, because it was a flow that I reuse and change only a few subflows.

Tried rebooting, unistalled and installed it again. Same error:

´´´´Microsoft.Flow.RPA.Desktop.Robin.SDK.ActionException: Failed to run PowerShell script. ---> System.ComponentModel.Win32Exception: The system cannot find the file specified
at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo)
at Microsoft.Flow.RPA.Desktop.Modules.System.Actions.SystemActions.RunPowershellScript(Variant powershellCode, Variant& scriptStandardOutput, Variant& scriptErrorOutput)
--- End of inner exception stack trace ---
at Microsoft.Flow.RPA.Desktop.Modules.System.Actions.RunPowershellScript.Execute(ActionContext context)
at Microsoft.Flow.RPA.Desktop.Robin.Engine.Execution.ActionRunner.Run(IActionStatement statement, Dictionary`2 inputArguments, Dictionary`2 outputArguments)

´´´´

The only thing I can think of is somehow the power automate desktop loses is internal reference (possibly memory leak?). My thanks in advance for any advise.

Looks like it can't find a certain file.
Could you please post the powershell script, doing that will help us help you 😊

Thanks for the reply @Highboy.
The Run Power shell scritp action only has the following code:

$variableName = "variableValue"
Write-Output $variableName

On my computer
OS Name Microsoft Windows 10 Pro
Version 10.0.19042 Build 19042
The weirdest thing is I don't have any issues when I connect to my remote machine and with my credentials I am able to run everything with:
OS Name Microsoft Windows Server 2016 Datacenter
Version 10.0.14393 Build 14393

As you said @Highboy, I reused the code of another flow, and at a certain point it gave me a error reading a file. Deleted the code in the action and pasted the above code.

So, if you create a new flow and paste the code into a powershell action, will it fail?

Can you copy the PAD actions themselves and paste the resulting text somewhere. Then compare. Maybe there's some corruption going on that can't be seen "with the naked eye"...?

Currently facing exactly the same issue. All powershell actions no longer work and throw the same error, even rudimental ones like creating a folder...
Any suggestions?
