redux选择器没有相应地筛选嵌套数组

我试图过滤Likes userId等于params.userId的帖子,现在我得到一个空数组。理想情况下,它应该得到params.userId喜欢的所有帖子。

选择器

export const getUserPosts = (params) => {
    return createSelector(
        postSelector,
        (state) => {
            const findIndex = state.posts.findIndex((x) => x.userId == params.userId);
            console.log(findIndex)
            // const likedPosts = state.posts.reduce((acc, cv) => {
            //     const newPosts = {
            //         Likes: cv.Likes.filter((item) => item.userId == params.userId)
            //     }
            //     const newerPosts = newPosts.Likes.length !== 0 ? newPosts.Likes : []
            //     console.log(newerPosts)

            //     return { acc, newerPosts }
            // }, [])
            // console.log(likedPosts)
            return state.posts.filter((item) => item.Likes.userId == params.userId)
        }
    )
}
