I'm trying to pass to the PowerShell script maps in vector. Unfortunately, instead of the expected array containig hashtable I get an array containing stings. Below I attach a sample configuration plan where you can see the problem.

set @Groups = @(%(key1:val1,key2:val2),%(key1:val3,key2:val4));

foreach %Group in @Groups
{
    Log-Information %Group.key1;
    Log-Information %Group.key2;
}

Execute-PowerShell >>
foreach ($Group in $Groups)
{
    Write-host PowerShellLoop
    Write-host $Group
    Write-host "IsHastable: $($Group -is [Hashtable])"
}
>>;

How to pass Groups variable so that PowerShell receives array containing hashtable?
