Проблемы с подключение MongoDB

Код:

const express = require('express');
const mongoose = require('mongoose');
    
const app = express();
const morgan = require('morgan');
    
mongoose.set("strictQuery", false);
mongoose.connect('mongodb://localhost:27017/nodetools',
                 { useNewUrlParser: true, useUnifiedTopology: true })
    .then((result) => console.log('connected to db'))
    .catch((err) => console.log(err));

Ошибка:
