Take PowerShell Output and use for error handling

Hello.

I'm executing a script on a remote PowerShell host, and I want to be able to act upon either the exit code or some other output text within a string variable to do something like log, or fail the workflow within vRO.

The example being that if i attempt to run a native windows command (e.g. dnscmd.exe) within my PowerShell script that returns "Access Denied" or similar, as the PowerShell script still completes successfully, so does the vRO workflow.

How can I forcibly fail the workflow when certain output criteria is met?

Thanks,


Dan

I knwo this is quite old, but to anyone else looking, this helped me sort out a return code I could use. I had to return value from Powershell, extract them using this link and then compare the values in the workflow. If they matched error messages, I simple threww and error in the workflow. Granted, you ahve to know what to check for...

One approach could be within your external script is within the end block use a switch statement to evaluate the exit code ($LASTEXITCODE) to select the appropriate action.

For Example:

End{

     Switch ($LASTEXITCODE){

          '0' {Write-Host 'success message'},

          '1' {throw 'error message'} ,

          '81' {Write-Host 'custom message'}

     }  # Switch ($LASTEXITCODE)

} # End
