O `RequestValidationError` contém o `body` que ele recebeu de dados inválidos.

Você pode utilizá-lo enquanto desenvolve seu app para conectar o *body* e debugá-lo, e assim retorná-lo ao usuário, etc.

Tente enviar um item inválido como este:

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

Você receberá uma *response* informando-o de que a data é inválida, e contendo o *body* recebido:
