Jmeter body request is not valid

Description

Hello guys, I was trying to generate Jmeter API tests from a YAML openapi 3.0.2. it seems everything ok but the request bodies; here is what I can see in the request body part:

${__javaScript("${registrationTypePut}".replace(/'/g\, '"'),)}

openapi-generator version

5.4.0

OpenAPI declaration file content or url

I got something like:

openapi: "3.0.2"

  title: company registration types API

Generation Details

I did generate it by a shell installed CLI command like:
openapi-generator-cli generate -i API.yml -g jmeter -o jmeter-client

on Ubuntu 20.04.4, JDK 11, mvn 3.6.3

Related issues/PRs

I don't know but the only issue I did find related to this one maybe be this
but in my case there is no empty body, I can see a piece of code, I think I was expecting example values.

Reproduce the JMeter generation with the provided OpenAPI YAML, openapi-generator 5.4.0, and the documented CLI command on Ubuntu. Inspect the JMeter generator output and its handling of request-body examples; done means the generated request contains a valid body rather than the shown JavaScript expression.
