我最近正在用React开发Web应用程序，并使用“nedb”作为数据库。我可以用$ node "the code path"运行下面的代码。但是，在localhost中，发生了以下错误。

ERROR

我更改了错误中的URL，因为StackOverFlow将其作为垃圾邮件拒绝。（https->H）
DatabaseComponent.js

const NeDB = require('nedb');

const db = {};
db.users = new NeDB({
  filename: 'src/database/users.db',
  autoload: true,
});

export const addUser = (props) => {
  const { name, email } = props;
  db.users.insert({ name, email }, (err, newDoc) => {
    console.log('[INSERT]');
    console.log(newDoc);
  });
};

export default { addUser };

EditDB.js

/* eslint-disable react/button-has-type */
import { React } from 'react';
import { useNavigate } from 'react-router-dom';
// eslint-disable-next-line no-unused-vars
import { addUser } from '../../backend/DatabaseComponent';

function EditDB() {
  return (
    <div className="editDB">
      <h1>EditDB</h1>
      <Buttons />
    </div>
  );
}

function Buttons() {
  const navigate = useNavigate();
  return (
    <div className="buttons">
      <button onClick={() => navigate(-1)}>back</button>
      <button onClick={({}) => addUser()}>create</button>
    </div>
  );
}

export default EditDB;

我在谷歌上搜索了这个错误，发现很多人通过修改webpack.config.js解决了这个错误。虽然我的项目中没有这个文件，可能是因为我用create-react-app创建了这个应用程序。有人能告诉我这个错误的解决方案吗？先谢谢你。
