Hi everyone,

can someone tell me how I can use the PSU App to transfer UNC paths (FullName) into a table via a New-UDForm? When I use the command Get-ChildItem -Path "\\server\sharename" -Directory, I always get the message that the path does not exist.
Additionally, when passing the path, it gets truncated, even though the variable I want to use shows the correct entry when I output it with Show-UDToast -Message.

New-UDApp -Title 'Test' -Content {

    $Session:FormResult = $null

    New-UDCard -Content {
        New-UDForm -Id 'form1' -Content {
            New-UDTextbox -Id 'txtBox1' -Label "UNC-Path" -FullWidth
            New-UDSelect -Label 'Choose depth' -Id 'DepthSelect' -Option {
                New-UDSelectOption -Name "1. depth" -Value 0
                New-UDSelectOption -Name "2. depth" -Value 1
                New-UDSelectOption -Name "3. depth" -Value 2
                New-UDSelectOption -Name "4. depth" -Value 3
            } -FullWidth
        } -OnSubmit {
                $Session:FormResult = @{
                UNCPath = $EventData.txtBox1
                Depth = $EventData.DepthSelect
            }
            Sync-UDElement -Id 'ResultCard'
        }
    }

    New-UDDynamic -Id 'ResultCard' -Content {

        if ($Session:FormResult){
            $UNCPath = $Session:FormResult.UNCPath
            $Depth = $Session:FormResult.Depth
        }

            $Folders = Get-ChildItem -Path $UNCPath -Depth $Depth -Directory
}

fixed the problem with: $UNCPath = [string]$Session:FormResult.UNCPath
