3093066 - NullPointerException error when trying to serialize a REST.Cycle object that encapsulates a request coming from a REST Server agent

Symptom

You see a NullPointerException error when trying to serialize a REST.Cycle object that encapsulates a request coming from a REST Server agent. When the object goes through an “MZ format tagged UDRs” encoder it generates a NullPointerException error. A similar issue happens when the object is stored into a session in an Aggregation agent and the agent tries to serialize on disk the REST.Cycle object.


On the stack trace, you can see the following:

java.lang.NullPointerException
    at com.digitalroute.mz.rest_server.udr.RestServerRequest_UDR.concatInternalMapList:138
    at com.digitalroute.mz.rest_server.udr.RestServerRequest_UDR.writeTo:178
