...then because `description` has a default value, if you **don't return anything** for that field, it will still have that **default value**.

### Model for Output Response Data { #model-for-output-response-data }

If you interact with the docs and check the response, even though the code didn't add anything in one of the `description` fields, the JSON response contains the default value (`null`):

在那之前，只支援使用單一範例的關鍵字 `example`。OpenAPI 3.1.0 仍然支援 `example`，但它已被棄用，且不是 JSON Schema 標準的一部分。因此建議你將 `example` 遷移為 `examples`。🤓
