It is Set-Strictmode that is causing the exception. If you comment that line out you won't get an error. But, I can see where it might help to improve the code in the function.

from psscripttools.

I can see where this could be a problem with an empty folder. But I can't duplicate the problem.

What version of PowerShell and Windows (I assume) are you running?

from psscripttools.

I run this code on Windows 11 and Windows Server 2019, results were the same.

Set-StrictMode -Version 3.0

$psversiontable
$Path = 'C:\Temp\EmptyFolder'
Remove-Item -Path $Path
New-Item -type Directory -Path $Path

$cPath = (Convert-Path -literalpath $path -ErrorAction Stop)
    
if (Test-Path -literalpath $cPath -ErrorAction Stop) {
    $d = [System.IO.DirectoryInfo]::new($cPath)
    $files = [system.collections.arraylist]::new()

    If ($psversiontable.psversion.major -gt 5) {
        #this .NET class is not available in Windows PowerShell 5.1
        $opt = [System.IO.EnumerationOptions]::new()
        $opt.RecurseSubdirectories = $True
        # https://docs.microsoft.com/en-us/dotnet/api/system.io.fileattributes?view=net-6.0
        $opt.AttributesToSkip = "SparseFile", "ReparsePoint"
        $data = $($d.GetFiles("*", $opt))
        if ($data.count -gt 1) {$files.AddRange($data)}
        elseif ($data.count -eq 1) {[void]($files.Add($data))}
    }
}
