即使正确更新了Redux状态，渲染方法中的Redux State为null

Question

我正处于反应的学习阶段，并创建一个小型应用程序，该应用程序从firebase表和更新的redux存储中获取用户愿望清单，并且我尝试通过render方法访问该redux存储，但是当我console.log this.props .wishlist 在呈现方法中显示为null。 Redux状态已正确更新。经过redx dev工具检查。 redux state screenshot

WhislistReducer-

export const fetchWishlist = (email)=> {
    return dispatch => {
        dispatch(fetchWishlistStart());
        let rawMovieId=[];
        let uniqueMovieIdList = [];
        const queryParams ='?orderBy="email"&equalTo="'+email+'"';
        axios.get('https://movie-project-6fc34.firebaseio.com/wishlist.json'+queryParams)
        .then (response=>{
            for(let key in response.data){
                rawMovieId.push(response.data[key].movieId)
            }
            uniqueMovieIdList =  [ ...new Set(rawMovieId) ];
            dispatch(fetchMovieDetailsForWishlist(uniqueMovieIdList))   
        })
        .catch(error=> {
            console.log(error);

export const setMovieDetailsForWishlist = (movieDetailsList)=> {
    return {
        type:actionType.SET_MOVIEDETAILS_WISHLIST,
