伙计们。我开始用redux创建异步操作，当我把异步操作放到调度中时，得到了一个错误：Argument of type '(dispatch: Dispatch) => Promise<void>' is not assignable to parameter of type 'AnyAction'.ts(2345)
异步操作：

import { updateCommentCounterAction } from "../store/commentCounter";
import { PostService } from "../API/PostService";
import { Dispatch } from "redux";

export const fetchComment = (idPost: string | undefined) =>{
    return async (dispatch: Dispatch) =>{
        const response = await PostService.getPost(idPost);
        dispatch(updateCommentCounterAction(response.comments))
    }
}

在应用程序中使用操作：

useEffect(() => {
    fetchPost();
    dispatch(fetchComment(idPost));
}, [])

我做错了什么？谢谢！
