Powershell script in PRTG

Hi All,

I try to use powershell to get some extended properties of all the files in my folder. I use the script below and from the powershell console it works fine. When PRTG runs it, it gives the error below:

You cannot call a method on a null-valued expression.
At C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXE\GetMovieTitles_GET.ps1:2 char:1
+ $com.Items() | ForEach-Object {
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException
    + FullyQualifiedErrorId : InvokeMethodOnNull

Below is the script im using:

$com = (New-Object -ComObject Shell.Application).NameSpace('\\my.machine\drive\folder\')
$com.Items() | ForEach-Object {
        New-Object -TypeName PSCustomObject -Property @{
            Name = $com.GetDetailsOf($_,0)
            Size = $com.GetDetailsOf($_,1)
            ItemType = $com.GetDetailsOf($_,2)
            Title = $com.GetDetailsOf($_,21)
            }
        } | Select-Object -Property Title, Name | Where-Object -Property Title -GT $false | Format-Table -HideTableHeaders -OutVariable get | Out-File -FilePath C:\Log\myoutfile.log

If ($get.Count -LE 0) {
                      Write-Host "0:Status OK - Everything is fine, nothing to see here."
                      }
If ($get.Count -GE 1) {
                      Write-Host "2:Status ERROR - Title(s) incorrect! Look in folder `"\\my.machine\C:\Log\myoutfile.log`" for the file(s) that have a title set."
                      }
