Cannot Generate Endpoints from Open API Swagger Petstore

[khajavi]

I converted this spec to JSON and tried to generate endpoints, but encountered the following errors. There may be some edge cases left to be sure the endpoint generation is fully functional.

Generating of enums does not work as well. In case of in place definition, it skips that completely and in case of object, it creates empty case classes with names of each enum type (in case of string enums) which leads to compilation errors. As I have looked at unit tests it seems, that generating openAPI from code with enum works as expected, so there is probably error when parsing yaml files and then generating enum (sealed trait to be precise)

I would just like to point out, that as great as this tool is, having issues with enum is complete blocker for being used in production with API first approach. @987Nabil is this something that someone outside of maintainers could do? Thanks
