Spotlight for SQL Server produces errors like this:

Action 'Action/{10AF3A64-01C7-4734-8872-E509CF35264E}/RunPowerShellScriptOperation/C:' failed : The term 'ƒ?oHighƒ??' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.At C:\Users\svc_sql_spotlight\AppData\Local\Temp\Spotlight4726869587809460271.ps1:2 char:1+ Invoke-Command -ComputerName 

1) Check if the PowerShell commands executed by the Spotlight on SQL Server are correct.

2) Store commands to PowerShell script and use calling "powershell C:\script.ps1" from "Run program" action instead of "PowerShell script" action.
