我正在嘗試呈現(xiàn)一個(gè)博客頁(yè)面以顯示所有 Storyblok 博客條目：這是我的 blog.js 頁(yè)面import React from "react"import Layout from "../components/layout"import Blogposts from "../components/BlogPosts"import StoryblokService from '../utils/storyblok-service'export default class extends React.Component {  state = {    stories: {    }  }  async getInitialStories() {    let { data: { stories } } = await StoryblokService.get('cdn/stories?starts_with=blog')    return stories  }  async componentDidMount() {    let stories = await this.getInitialStories()    if(stories.content) this.setState({ stories })    console.log(stories)    setTimeout(() => StoryblokService.initEditor(this), 200)  }  render() {    return (      <Layout>        <Blogposts stories={this.state.stories.content} />      </Layout>    )  }}console.log(stories)返回我的博客文章Blogposts 組件看起來像這樣import React from 'react'const BlogPosts = (stories) => (    <ul>      {stories.map((story) => (          <li key={story._uid}>            { story.title }          </li>        )      )}    </ul>)export default BlogPosts 但是當(dāng)我運(yùn)行它時(shí)，我得到了這個(gè)錯(cuò)誤。TypeError: undefined is not a function (near '...stories.map...') BlogPosts src/components/BlogPosts.js:52 |   3 | const BlogPosts = (stories) => (  4 |> 5 |     <ul>  6 |       {stories.map((story) => (  7 |           <li key={story._uid}>  8 |             { story.title }任何幫助將不勝感激！謝謝。
