Issue when running ExecuteStateless

[#1]

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,

This are the details of the executeStateless process, 

When running i can see following error,
