NullPointerException in SNMP Trap Producer Component
Hi,
currently I am working on a project where I receive OPC UA data and send them via SNMP to a PRTG monitoring system. I already created the routes between OPC UA datapoints and a SNMP client (with an unique OID). The problem here is the connection to the PRTG monitoring system. When I start the connection I get a NullPointer Exception on the the SnmpTrapProducer. It seems like I cannot create a trap of type PDU in SNMPTrapProducer.java
I figured out that the PDU trap that is created in SnmpTrapProducer.process(Exchange exchange) returns the NullPointerException(you can see the parts of the class in the picture). I tried different approaches like changing message body types or different ports as well as on ip addresses. But I still get the NullPointerException.
It seems like the apache camel snmp component call on the snmp4j library doesn't work as expected.
Further information about my project settings:
* Camel Version: 2.24.2
* Spring Boot: 2.1.7
Any help is greatly appreciated!
Best, Stefan
