                This is particularly useful when automatically generating clients or

En algunos casos, todavía podrías tener que usar la versión de `dataclasses` de Pydantic. Por ejemplo, si tienes errores con la documentación de la API generada automáticamente.

En ese caso, simplemente puedes intercambiar los `dataclasses` estándar con `pydantic.dataclasses`, que es un reemplazo directo:
