@ghilainm,

This is duplicate of: https://github.com/springdoc/springdoc-openapi/issues/2623 that was already answered.

Hello @bnasslahsen , I had seen that ticket and I have already added the requested dependency to com.fasterxml.jackson.module:jackson-module-kotlin.

@ghilainm,

Well, check your dependencies to make sure it's correctly loaded. If it's not working, Feel free to provide a github repo with Minimal, Reproducible Example - with HelloController that reproduces the problem.
