我一直得到一个“Render error，undefined is not a function”，我不知道是什么原因导致的。

{
     "count": 3,
     "next": "http://0.0.0.0:8000/post?limit=1&offset=1",
     "previous": null,
     "results": [
        {
           "id": 0,
           "title": "title",
           "description": "description",
           "img": "https://linktoimage.jpg"
        }
     ]
}

我的家

const Home = () => {

const { data, isLoading, isError, hasNextPage, fetchNextPage } =
 useFetchPost();
if (isLoading) return <Text>Loading...</Text>; 
if (isError) return <Text>An error occurred while fetching data</Text>;
const flattenData = data.pages.FlatMap((page) => page.data);

const loadNextPageData = () => {
 if (hasNextPage) {
   fetchNextPage();
 }
};

return (

  <FlatList
    keyExtractor={(item) => item.id}
    data={flattenData}
    renderItem={({ item }) => <Post post={item} />}
    estimatedItemSize={2}
    onEndReached={loadNextPageData}
  />
 );
};export default Home;

然后使用FetchPost

import { useInfiniteQuery } from "@tanstack/react-query";
 export default function useFetchPost() {
 const getPosts = async ({ pageParam = 0}) => {
 const res = await (
  await fetch(
    `http://0.0.0.0:8000/post?limit=1&offset=${pageParam}`
  )
).json();   
 
return {
  data: res,
  nextPage: pageParam,
};
};  return useInfiniteQuery(['post'], getPosts, {
getNextPageParam: (lastPage) => {
        if (lastPage.data.length < 1) 
    return undefined;
  return lastPage.nextPage;
},
});
}

最后是错误跟踪：

ERROR  TypeError: undefined is not a function

到目前为止，我已经尝试了多种解决方案，但没有任何工作，我认为它有一个问题，从项目中获取信息，我尝试使用不同的返回，而不是useFetchPost中getNextPageParam中的undefined。
