-`RequestValidationError` is a sub-class of Pydantic's `ValidationError`.
+`RequestValidationError` is a **FastAPI-specific exception** (it inherits from `fastapi.exceptions.ValidationException`). It is **not** a sub-class of Pydantic's `ValidationError`.
**FastAPI** uses it so that, if you use a Pydantic model in `response_model`, and your data has an error, you will see the error in your log.
