* Converter o modelo copiado em algo que possa ser armazenado no seu banco de dados (por exemplo, usando o `jsonable_encoder`).
    * Isso é comparável ao uso do método `.model_dump()`, mas garante (e converte) os valores para tipos de dados que possam ser convertidos em JSON, por exemplo, `datetime` para `str`.
* Salvar os dados no seu banco de dados.
* Retornar o modelo atualizado.

* Convert the copied model to something that can be stored in your DB (for example, using the `jsonable_encoder`).
    * This is comparable to using the model's `.model_dump()` method again, but it makes sure (and converts) the values to data types that can be converted to JSON, for example, `datetime` to `str`.
* Save the data to your DB.
* Return the updated model.

# Backporting fixes

* Cherry-picking is discussed in the original PR and subject-matter experts have approved the backport.
    * Behavioral changes should be highly scrutinized, while typo fixes don't require that level of scrutiny.
* It is preferable that cherry-picks are done by the istio-testing bot.
    * Automated cherry-picks do not need subject-matter experts to approve if discussed in the original PR.
