我想在mongodb数据库中插入nodejs文件中的一些数据。但是我得到如下的错误消息。我该怎么做？我基本上是Mongodb和NodeJS的初学者。我在stackoverflow上搜索了一些文档和帖子，但没有一个对我有用。

const {
  MongoClient
} = require('mongodb');
// or as an es module:
// import { MongoClient } from 'mongodb'

// Connection URL
const url = 'mongodb://127.0.0.1:27017';
const client = new MongoClient(url);

// Database Name
const dbName = 'fruitsDB';

async function main() {
    // Use connect method to connect to the server
    await client.connect();
    console.log('Connected successfully to server!!!!');
    const db = client.db(dbName);
    const collection = db.collection('fruits');

    // the following code examples can be pasted here...
    collection.insertMany([
        {
          name: "Apple",
          score: 8,
          review: "Great fruit"
        },
        {
          name: "Orange",
          score: 6,
          review: "Kinda sour"
        }
      ])

      return 'done.';
}

main()
  .then(console.log)
  .catch(console.error)
  .finally(() => client.close());

这是我执行的命令。

$ FruitsProject % node app.js

这是我终端上的信息。
