AmbiguousParameterSet with ForEach-Object -parallel

Hello,

I have this error when trying to use parallele tasks. Can anybody help on this please?

$TimeDuration = [System.Diagnostics.Stopwatch]::StartNew()

[System.Collections.ArrayList]$ArrayWithHeader = @()
$Date = Get-date -Format "yyyy_MM_dd HH-mm"
$ListOldOSesPath = ".\ListOldOSes\$date"
#Check backup folder
if (-Not(Test-Path -Path $ListOldOSesPath)) {New-Item -ItemType Directory $ListOldOSesPath -Force }


$complist = Get-ADComputer -Filter * -Property OperatingSystem,name,enabled,Description,distinguishedname #| Where-Object -Property name -EQ "SRVCOPWDC02P"
$total = $complist.count
$count = 1

#Workflow TestParallel{
$complist | ForEach-Object -parallel{
 #foreach ($comp in $complist){
          $PC = $_.name
          write-host "working on $PC $count/$total"
 
          #write-host "working on $_ "

            $pingtest = Test-Connection -ComputerName $PC -Quiet -Count 1 -ErrorAction SilentlyContinue
            #$Result = [pscustomobject]@{'OS'=$($_.OperatingSystem);'Computer_Name'=$($_.name);'DN'=$($_.distinguishedname);'enabled'=$($_.enabled);'Description'=$($_.Description);'Reacheable'=$($pingtest)}

            $ArrayWithHeader.add([pscustomobject]@{'OS'=$_.OperatingSystem;'Computer_Name'=$_.name;'DN'=$_.distinguishedname;'enabled'=$_.enabled;'Description'=$_.Description;'Reacheable'=$pingtest}) | Out-Null

            #$ArrayWithHeader.add($Result) | Out-Null

            #$Result=$null
            $count += 1
       }
#}

#TestParallel

$ArrayWithHeader | export-csv -path "$ListOldOSesPath\_ListOldOSes.csv" -NoTypeInformation -Append -delimiter ";"
Invoke-Item "$ListOldOSesPath"

#Show script processing time
$TimeElapsed = $TimeDuration.elapsed.ToString('dd\.hh\:mm\:ss')
$TimeDuration.stop
$TimeElapsed

pause

I'm using PS 7.

Thank you.
