I am trying to run flow using executestateless by following tutorial here, (190) Kafka Exactly Once with NiFi - YouTube

Nifi version: 1.16.3 running on kubernetes

My processor is as follow,

And for ProcessXMLStageDB,

ConsumeJMS connected to IBM MQ. Jar file and truststore file to connect with IBM MQ is included in the Nifi image, i.e. I create custom image to add the necessary requirement to connect to IBM MQ.

This is my ExecuteStateless,
