我使用redux状态创建了一个登录函数，但问题是当我登录时，我得到一个错误消息。在我的Sidebar.jsx中。看起来，我不能立即呈现数据admin，
TypeError：无法读取null的属性（阅读“category_affiliation”）
Sidebar.jsx

const Sidebar = () =>{

  const { admin } = useSelector((state) => state.admin);
  let techSuperAdmin = admin && admin.techAdmin ? admin.techAdmin : false;
  let techAdminCategory = admin && admin.category_affiliation ? admin.category_affiliation : null;
}

字符串
这是我的账号

const handleLogin = async (e) =>{
    e.preventDefault()
    try {
      await LoginUser(userAdmin, dispatch)
    } catch (error) {
      console.log(error)
    }
  }

MyAdminSlice.jsx

export const adminSlice = createSlice({
    name: 'admin',
    initialState: {
        admin: null,
        isFetching : false,
        isError: false,
        isSuccess: false,
        isUpdated: false,
        isMessage: "",
    },
    reducers: {
        resetState: (state) =>{
            state.admin = null;
            state.isFetching = false
            state.isError = false
            state.isSuccess = false
            state.isUpdated = false
            state.isMessage = ""

        loginStart: (state)=>{
            state.isFetching = true;
            state.isError = false;

        loginSuccess: (state, action) =>{
            state.isFetching = true;
            state.isSuccess = true;
            state.admin = action.payload,
