我想在前端显示帖子详情。我的 api 显示的帖子详情如下，在 postman 中捕获：

"message": "Posts fetched successfully!",
    "posts": {
        "_id": "61f05f676793d49f466e7aaa",
        "title": "Liberal Arts Student Sample",
        "content": "The three-page.",
        "creator": {
            "_id": "61cd99efa0b8d616a7a53ce1",
            "createdAt": "2021-12-30T11:37:19.041Z",
            "updatedAt": "2022-01-06T14:35:48.801Z",
            "__v": 0,
            "bio": "user bio",
            "name": "username"
        },
        "Comments": [],
        "created": "2022-01-25T20:36:55.095Z",
        "createdAt": "2022-01-25T20:36:55.096Z",
        "updatedAt": "2022-01-25T20:36:55.096Z",
        "__v": 0
    }
}

我想在前端展示此帖子详情，代码如下：

export default function PostDetail() {
    const { postId } = useParams();
    const post = useSelector((state) => state.post)
    const dispatch = useDispatch();
    const { title, content,creator, created } = post;
    const fetchPostDetail = async (id) => {
        const response = await axios.get(`http://localhost:5000/api/articles/post/${id}`, { post })
            .catch(err => {
                console.log(err);
            })
        dispatch(selectedPost(response.data.posts));
              }

    useEffect(() => {
        fetchPostDetail(postId)
    }, [])


    return (
        <div>
            <h1>Post Detail</h1>
            <div>
                <h2>{title}</h2>
                <i>posted in {created}</i>
                 <li>Created by {creator.map((m,i)=>(
<b key={i}>{m.name}</b>
                 ))}</li> 
                <p>{content}</p>
            </div>
        </div>
    );
}

有三个错误：

1. 未捕获的类型错误：创建者未定义
2. 组件中发生上述错误：
3. 未捕获的类型错误：创建者未定义

如果我将
