Ah right - the issue is due to the serialization class try amending the serializer key in producer config to : org.apache.kafka.common.serialization.StringSerializer

and give it a try - if you still see the issue, can you share the jmeter.log file (you can remove the crucial info if something is in there)

rollno748 commented 1 year ago

I am releasing a newer version (v1.2) of this plugin - which is having the change for default serlializer key and value Also with some error handling changes.

meanwhile you can download it from the tags or from here: https://github.com/rollno748/di-kafkameter/releases/download/1.2/di-kafkameter-1.2.jar

Upon your confirmation, I will close this issue

I downloaded version 1.2, but the same problem still occurred. I will send jmeter.log to you jmeter.log

rollno748 commented 1 year ago

From the jmeter.log - which you have shared - I could see that your key serializer config is not an instance image

As I said earlier, you need to replace the key serializer in Producer config like below

Hopefully this will resolve your issue
