Você pode declarar vários parâmetros `File` e `Form` em uma *operação de caminho*, mas não é possível declarar campos `Body` para receber como JSON, pois a requisição terá o corpo codificado usando `multipart/form-data` ao invés de `application/json`.

Isso não é uma limitação do **FastAPI** , é parte do protocolo HTTP.

You can override it by returning a `Response` directly as seen in [Return a Response directly](response-directly.md){.internal-link target=_blank}.
