[SOLVED] I'm getting this error during connecting mongoose to nodejs

I'm getting this error during connecting mongoose to nodejs

I am New in Nodejs. I have just started learning about MongoDB and I am trying to host my nodejs application locally via MongoDB Server 6.0 (without using mongoose or atlas).

const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/e-commerce')

And I am getting this error.

D:\Ecommerce-Dashboard\server\node_modules\mongoose\lib\connection.js:755
err = new ServerSelectionError();
