Openapi 示例返回 生成问题

[TnZzZHlp]

#[endpoint(
    responses((
        status_code = 200,
        description = "Success response",
        content_type = "application/json",
        example = json!({"id": 1, "name": "bob the cat"}),
    ))
)]
async fn hello(name: QueryParam<String, false>) -> String {
    format!("Hello, {}!", name.as_deref().unwrap_or("World"))
}

这段代码应该生成示例返回，但是对应生成的json文件中没有示例返回，求教一下各位大佬，这是bug还是我的写法问题
