Generator doesn't generate nullable parameters always #132
Description
Description of the bug
Generator doesn't generate nullable parameters always - some classes have some parameters nullable when generated (ex: String? name), but not all classes and that is becoming big issue for an app. I have to change them manually every time when i generate it again (and no, i can't put it in openiapi-ignore file, because that classes will change on backend).
Steps to reproduce
Just run generator as usually
Expected behavior
To have all parameters of the class generated as nullable types
