I am using the maven plugin openapi-generator-maven-plugin (python generator), to generate Python code that includes UUID fields. Since 7.15 version of this plugin, the to_json method of the generated python object containing an UUID field leads to this error: Object of type UUID is not JSON serializable error

There is an example to reproduce the issue

components:
  schemas:
    MyObject:
      type: object
      properties:
        id:
          type: string
          format: uuid

from my_api.model.my_object import MyObject
import uuid

obj = MyObject(id=uuid.uuid4())
json_str = obj.to_json()
