Então, um objeto `datetime` teria que ser convertido em um `str` contendo os dados no <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">formato ISO</a>.

Da mesma forma, este banco de dados não receberia um modelo Pydantic (um objeto com atributos), apenas um `dict`.

Você pode usar a função `jsonable_encoder` para resolver isso.
