New-ADUser : The object name has bad syntax

I've already seen the other thread, but that was a little bit confusing for me.

So my script looks like this:

#Users and Groups
Import-Module ActiveDirectory
$csvfile = Join-Path(Split-Path $MyInvocation.MyCommand.Path) "ADUsers.csv"
$csv = Import-Csv "$csvfile" -Delim ';'
New-ADOrganizationalUnit -Name SWDTest -Path "DC=swisscomswd, DC=local" -ProtectedFromAccidentalDeletion $false
New-ADOrganizationalUnit -Name Users -Path "OU=SWDTest, DC=swisscomswd, DC=local" -ProtectedFromAccidentalDeletion $false
New-ADOrganizationalUnit -Name ServiceAccounts -Path "OU=SWDTest, DC=swisscomswd, DC=local" -ProtectedFromAccidentalDeletion $false
Foreach ($line in $csv)
{
$pw = ConvertTo-SecureString -AsPlainText -Force -String $line.Passwort
$pwsecure = `
    [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pw)
$HiddenPW = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($pwsecure)
New-ADUser -Name $line.LastName -Surname $line.FirstName -DisplayName "$line.Display Text" -AccountPassword $line.HiddenPW -Description $line.Description -SamAccountName $line.AccountID -Path "OU=$($line.OE), DC=swisscmswd, DC=local"
}
Write-Host -Fore Green "ADDS installed!"

And my csv looks like this:

I still get the error (written in title). Anyone knows why? The message appears as many times, as it has users.

The following is my signature:
