Ohh I have noticed this pull request is totally invalid since the clietns are generated with openapi-generator. I did check the feature is available in newer version. I guess I need to figure out how to setup the dev env generate with a new version. I am wondering if upgrading from openapi-generator 4 to 7 is a huge task.
