我在redux状态下将帖子定义为数组，但当我试图将其Map到组件代码中时，它似乎不起作用。下面是我的Redux状态代码：

import {createSlice} from "@reduxjs/toolkit";

const initialState = {
    mode:"light",
    user:null,
    token:null,
    posts:[]
};

export const authSlice = createSlice({
    name:"auth",
    initialState,
    reducers:{
        setMode: (state)=>{
            state.mode = state.mode === "light" ? "dark":"light"
        },
        setLogin: (state,action)=>{
            state.user  = action.payload.user;
            state.token = action.payload.token;

        },
        setLogout:(state)=>{
            state.user = null;
            state.token = null;
        },

        setFriends:(state,action)=>{
            if(state.user){
                state.user.friends = action.payload.friends
            }
            else{
                console.error("User friends non-exsistant")
            }

        },
        setPosts:(state,action)=>{
            state.posts = action.payload.posts;
        },
        setPost:(state,action)=>{
            const updatedPosts = state.posts.map((post)=>{
                if(post._id === action.payload.post_id) return action.payload.post;
                return post;
            });
            state.posts = updatedPosts;
        }
    }

 })

 export const {setMode , setLogin ,setLogout,setFriends,setPosts,setPost}= authSlice.actions;

 export default authSlice.reducer;

这是我的组件代码，我已经正确地使用了Useselector()函数来抓取posts数组，但它仍然给出了错误，Map()不是一个函数，我也正确地实现了Redux，并将我的应用程序 Package 在Provider标签中。

const PostsWidget = ({ userId, isProfile = false }) => {
  const dispatch = useDispatch();
  const posts = useSelector((state)=> state.posts);
  const token = useSelector((state) => state.token);

Here is the map code

`return (
    <>
      {posts.map(
        ({
          _id,
          userId,
          firstName,
          lastName,
          description,
          location,
          picturePath,
          userPicturePath,
          likes,
          comments,
        }) => (
          <PostWidget
            key={_id}
            postId={_id}
            postUserId={userId}
            name={`${firstName} ${lastName}`}
            description={description}
            location={location}
            picturePath={picturePath}
            userPicturePath={userPicturePath}
            likes={likes}
            comments={comments}
          />
        )``

我本以为它能工作，但不知道为什么它给了我一个错误。
