Serial numbers for Cisco switches / Stack Switches

I am trying to pull serial numbers for stack switches and other devices using on Solarwinds 2020.2.6

SELECT OrionNodes.Caption, OrionNodes.DetailsUrl, OrionNodes.Status, OrionNodes.ChildStatus, NcmEntityPhysical.EntityName, OrionNodes.IP_Address, OrionNodes.CustomProperties.ZL_Location, OrionNodes.CustomProperties.ZL_Region, OrionNodes.CustomProperties.ZN_Role,
OrionNodes.CustomProperties.ZN_Edge_Device, NcmEntityPhysical.EntityDescription, NcmEntityPhysical.Serial, NcmEntityPhysical.Manufacturer, NcmEntityPhysical.Model, NcmNodeProperties.NodeComments, OrionNodes.SysName, OrionNodes.NodeDescription, OrionNodes.Location, OrionNodes.Contact, OrionNodes.MachineType, OrionNodes.LastBoot, OrionNodes.IOSVersion
FROM NCM.NodeProperties AS NcmNodeProperties
INNER JOIN Orion.Nodes AS OrionNodes ON NcmNodeProperties.CoreNodeID=OrionNodes.NodeID
LEFT JOIN NCM.EntityPhysical AS NcmEntityPhysical ON NcmEntityPhysical.NodeID=NcmNodeProperties.NodeID AND NcmEntityPhysical.EntityClass='3'
WHERE (OrionNodes.Vendor='Cisco'

but i dont get any serial numbers or manufacturer or model numbers (NcmEntityPhysical.Serial, NcmEntityPhysical.Manufacturer, NcmEntityPhysical.Model)  - These 3 are not working

it used to work on 2020.2.5 - is there anything wrong in above syntax?
