Use the below code. Powershell is a great language, it can do virtually anything.
This will work.
Connect-WfaCluster $Cluster
$vol = Get-NcVol -Name $VolumeName -Vserver $VserverName
$snaplist = $vol | Get-NcSnapshot | Out-String
Get-WFALogger -Info -message $("Vserver: " + $VserverName + " Volume: " + $VolumeName + " Snapshots:" + $snaplist)
Add-WfaWorkflowParameter -Name "SnapList" -Value $snaplist -AddAsReturnParameter $truesinhaa
