- **Description**: The pydantic schema fields are supposed to be optional but the use of `...` makes them required. This causes a `ValidationError` when running the example code. I replaced `...` with `default=None` to make the fields optional as intended. I also standardized the format for all fields.
- **Issue**: n/a
