null-valued expression error

[fd1911]

Hello there!
I'm developing a Dashboard where I query an Active Directory.
After the query the name and distinguishedname are passed to the -options of the New-UD Selector.
$arrayArgDistrolist= @( $grupo = get-adobject -Filter 'ObjectClass -eq "group"' -SearchBase "OU=Arg,OU=Distribution Groups,OU=Company,DC=company,DC=local" | Select-Object Name,DistinguishedName foreach ($grupos in $grupo) { $grupoArgDN= $grupos.DistinguishedName $grupoArgName = $grupos.Name New-Object psobject -Property @{label ="`"$grupoArgName`""; value ="`"$grupoArgDN`""} } ) New-UDSelector -id "selectorARG" -Options {$arrayArgDistrolist}
The $arrayArgDistrolist variable contains a lot of items like this example (write-host $arrayArgDistrolist) equals to "@{label="OfficeHQ"; value="CN=officeHQ,OU=Argentina,OU=Distribution Groups,OU=company,DC=Company,DC=local"} and a lot more of items.

I really don't know what I'm doing wrong here.

I've read the documentation and based on the examples this should work, given that $arrayArgDistrolist contains values like the examples.
I can't hardcode all the groups because it's from an AD and in the future, some will be added and maybe later some deleted. And also it will be a long script haha.

This is the second or third time I post an issue on GitHub, so... apologies if I misspell something. English is not my main language.
I'd appreciate the help!

Thanks!!!!!!
