How to access jmeter variable in pepper-box producer?

I am trying to test my kafka-cluster using jmeter and pepper-box pluging.

I am using jmeter and pepper-box plugin for the first time.so excuse me if you feel i am asking some non-sense questions.

I have written a Bean shell pre-processor and there i put UUID in a variable and mark it as jmeter variable

import java.util.UUID;
vars.put("msgUuid",UUID.randomUUID().toString());


now when i am trying to use this variable in my pepper box producer and use this "msgUuid" variable in it then it gives me error saying

symbol: variable msgUuid location: class
MessageIterator1530514979627 1 error Uncaught Exception
java.lang.ClassFormatError: Truncated class file. See log file for
details.

The sample producer is

{
"message_id": "${{msgUuid}}",
"type": "chat",
"sender": "xxx",
"receiver": "yyy",
"stype": "text",
"xml": "message"
"timestamp": "{{TIMESTAMP()}}"
}


Can you please guide me how to fix this?

Thanks in advance.

You should refer to Jmeter variables like this ${msgUuid} NOT ${{msgUuid}}.

${msgUuid}

${{msgUuid}}

Also you can use Jmeter function ${__UUID}directly instead of using beanshell code.

${__UUID}

You can find more information about jmeter variables and functions in Jmeter usermanual
