Para isso, **FastAPI** fornece uma função `jsonable_encoder()`.

## Usando a função `jsonable_encoder`

Vamos imaginar que você tenha um banco de dados `fake_db` que recebe apenas dados compatíveis com JSON.

Por exemplo, ele não recebe objetos `datetime`, pois estes objetos não são compatíveis com JSON.
