e.preventDefault 不是函数（React）

Question

我正在使用 React 制作一个将向 MongoDB 发送 POST 的表单，当我开始尝试填写表单时，会发生以下错误：

e.preventDefault is not a function
TypeError: e.preventDefault is not a function
    at handleChange (http://localhost:3000/main.451f9e824d0c94815e46.hot-update.js:96:7)
    at http://localhost:3000/static/js/bundle.js:75093:9

    at http://localhost:3000/static/js/bundle.js:64750:23
    at http://localhost:3000/static/js/bundle.js:75552:5

这是preventDefault所在的代码：

const handleSubmit = async (e) => {
    e.preventDefault();

    const res = await fetch("http://localhost:5001/client/projects", {
      method: "POST",
      body: JSON.stringify(project),
      headers: { "Content-Type": "application/json" },
    });

    const data = await res.json(project);
    console.log(data);
    console.log(project);
  };

const handleChange = (e) => {
    e.preventDefault();
    setProject({ ...project, [e.target.name]: e.target.value });
  };

非常感谢所有能帮助我的人:)
