Si tienes una app de FastAPI antigua, podrías estar usando Pydantic versión 1.

FastAPI versión 0.100.0 tenía compatibilidad con Pydantic v1 o v2. Usaba la que tuvieras instalada.

FastAPI versión 0.119.0 introdujo compatibilidad parcial con Pydantic v1 desde dentro de Pydantic v2 (como `pydantic.v1`), para facilitar la migración a v2.

FastAPI 0.126.0 eliminó la compatibilidad con Pydantic v1, aunque siguió soportando `pydantic.v1` por un poquito más de tiempo.

Il est conçu pour avoir des fonctions qui reçoivent deux paramètres, une « requête » et une « réponse ». Ensuite, vous
« lisez » des parties de la requête et « écrivez » des parties dans la réponse. En raison de cette conception, il n'est
pas possible de déclarer des paramètres de requête et des corps avec des indications de type Python standard comme paramètres de fonction.

            assertEquals(Integer.MAX_VALUE, response.getTotalBytesWritten());
        }

        @Test
        @DisplayName("Should handle partial copy operations")
        void testPartialCopyOperation() throws SMBProtocolDecodingException {
            // Simulate partial copy where not all requested bytes were copied
            byte[] buffer = createValidCopyChunkResponse(3, // Only 3 chunks written (maybe less than requested)

JSON Schema n'avait pas `examples`, donc OpenAPI a ajouté son propre champ `example` à sa version modifiée.

OpenAPI a également ajouté les champs `example` et `examples` à d'autres parties de la spécification :

* [`Parameter Object` (dans la spécification)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object) qui était utilisé par les éléments FastAPI :
    * `Path()`

Se você tem uma aplicação FastAPI antiga, pode estar usando o Pydantic versão 1.

O FastAPI versão 0.100.0 tinha suporte ao Pydantic v1 ou v2. Ele usaria aquele que você tivesse instalado.

O FastAPI versão 0.119.0 introduziu suporte parcial ao Pydantic v1 a partir de dentro do Pydantic v2 (como `pydantic.v1`), para facilitar a migração para o v2.

O FastAPI 0.126.0 removeu o suporte ao Pydantic v1, enquanto ainda oferece suporte a `pydantic.v1` por mais algum tempo.
