EUWebMonitorTransactionMetrics monitoringAgent returns null

Hi

Can somebody explain me why the
o2.get("monitoringAgent/name") returns null for a EUWebMonitorTransactionMetrics object?

and yet the webmonitoragent is showing properties in the script console

For an FTR object it seems to be working

def sb = new StringBuilder()
//FTR
def o1=server.TopologyService.getObject('68ef8899-10c2-4a7e-938a-0c6b21712935')
sb.append(o1.get("monitoringAgent"))
sb.append("\n")
sb.append(o1.get("monitoringAgent").type)
sb.append("\n")
sb.append(o1.get("monitoringAgent").name)
sb.append("\n")
sb.append("\n")
//WEBMONITOR
def o2=server.TopologyService.getObject('0c34e675-aad0-4fb2-9075-6160ac94a44b')
sb.append(o2.get("monitoringAgent"))
sb.append("\n")
sb.append(o2.get("monitoringAgent").type)
sb.append("\n")
sb.append(o2.get("monitoringAgent/name"))

return sb
