need to EXPORT VM from Capacity Tier to file

Hello

I need to script an exportation of Capacity Tier BAckup

I use this command to get the ID of the lastest backup of a VM ( here frhagfs7 )

$moi=Get-VBRSOBRObjectStorageRestorePoint -CapacityTier -name frhagfs7 |  Sort-Object {$_.CreationTime} -Descending | Select-Object -First 1

but unfortunatly the export command never works :

Export-VBRBackup -RestorePoint $moi -Dir "E:\TEST"

Export-VBRBackup : Cannot bind parameter 'RestorePoint'. Cannot convert the "FRHAGFS7" value of type
"Veeam.Backup.PowerShell.Infos.VBRSOBRObjectStorageRestorePoint" to type "Veeam.Backup.Core.COib".
