I have tried this

var snmpResult = SnmpService.retrieveTriggerData(trigger);

var trapData = System.getModule("com.vmware.library.snmp").processSnmpResult(snmpResult);

//trapData = data;

//System.log("Enterprise: " + snmpResult.enterprise);

System.getModule("com.vmware.library.snmp").logResult(trapData);

var MessageOID = "1.3.6.1.4.1.6876.4.5.1.2.9.0";

var wfId = "ee5f566a-8177-4e00-bf4a-edff97a6f313";

// We extract the VM name out of the SNMP TrapData

var SNMPTrap;

for (var x = 0; x < trapData.length; x++) {

var prop = trapData[x];

if (prop.get("oid") == MessageOID) {

SNMPTrap = prop.get("obj.1.metric");

break;

}

}

System.log(SNMPTrap)

ALL I Get is Null but it works on other OIDs
