Hi,

I am trying to run a python script using Run powershell script but it is not working in unattended mode. The user does not have admin rights on the server. I am providing the python exe path, python script path and the input variable.

Please suggest if there is a fix to it.

Is that showing any error? Please share screenshot (hide all sensitive data) of your flow and how you are calling python script from PowerShell.

Hi @asharma1 !

Try this:

& '%py_run%' '%python_path%' %TextAsNumberLast%

I hope this helps.
