Trap Listener is not catching traps with varbinds with type OID

[dushyantbangal]

I have a XUPS MIB, and I'm sending traps via iReasoning MIB Browser. I'm receiving traps with Integer and OctetString in varbinds.

However, when I send the xupsAlarm trap, which has OID type of varbinds, the trap listener doesn't ever hit the on('trap',callback) event.

UPDATE
Its not working only when I have the OID value upto 2 hierarchy, like .1.2.
Its working when I put the value like .1.2.3.

Can someone find out if its snmpjs issue or iReasoning issue?
