ERROR o.a.j.t.JMeterThread: Error while processing sampler: 'RPC Response'. java.lang.NullPointerException: null

[albertoaus]

Hi, I'm using the plugin to do some tests, thank you very much for sharing it because it is a good job. I think I have found a bug when a user uses a consumer in an auto delete queue.In my tests I have the queue with one message (see rabbitMQ picture) and after execute the AMQP Consumer in JMeter, the message is consumed but there is an error in JMeter and I can not see the result of the response.
