这是我的代码：

import Base from "./Base";
import axios from "axios";
import { createData } from "../../utils";
import { useState, useEffect } from "react";

export default function Today(props) {
  const [scoops, setScoops] = useState(0);

  //Fetch api/scoops/today
  const fetchScoops = async () => {
    const res = await axios.get("http://localhost:8000/api/scoops/today/");
    setScoops(res.data);
  };
  useEffect(() => {
    fetchScoops();
  }, []);

  console.log(scoops[0]);

  const rows = [
    createData(0, 1, scoops[0].title, "http://example.com"),
    createData(1, 2, "Paul McCartney", "http://example.com"),
    createData(2, 3, "Tom Scholz", "http://example.com"),
    createData(3, 4, "Michael Jackson", "http://example.com"),
    createData(4, 5, "Bruce Springsteen", "http://example.com"),
  ];

  return <Base rows={rows} duration="Today" />;
}

这是控制台返回的内容：

> undefined
> Today.js:20 {url: 'http://localhost:8000/api/scoops/1/', title: 'Hello World!', rank: 0, created_at: '2021-10-05T04:44:52.027336Z', updated_at: '2021-10-05T04:44:52.027336Z'}

问题是当我刷新页面时，我收到以下错误消息：

TypeError: Cannot read properties of undefined (reading 'title')

非常感谢您的帮助！
