i am having an error indicating a closed connection after a kafka consumer. In my consumer i am calling a service and when trying to fetch items from database i am facing this stack error :

org.springframework.kafka.listener.ListenerExecutionFailedException: Listener method ‘public void com.acteos.tms.eventbus.listeners.KafkaTourEventListener.listenTourWaypointsUpdatedEvent(com.acteos.tms.eventbus.avro.tour.TourWaypointsUpdatedEvent,java.lang.String,java.lang.String,java.lang.String,java.lang.String)’ threw exception
