Hello @Vimal_Kumar_G, Welcome to the MongoDB community forum,

The error says, provided url argument has a non-string value so make sure by printing/consol the url property has the correct value or not.

More debugging details would be great if still not resolved the problem.

This is my seed.js code

const { faker } = require('@faker-js/faker');
const { MongoClient } = require('mongodb')

const _ = require("lodash");

const { connection } = require('mongoose');

async function main() {

    const uri = 'mongodb://localhost:27017';

    const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });

    try {

        await  client.connect();
        const productsCollection = client.db("e-canteen").collection("products");
        const categoriesCollection = client.db("e-canteen").collection("categories");
        let categories = ['breakfast', 'lunch', 'dinner', 'drinks'].map((category) => { return { name: category } });
        await categoriesCollection.insertMany(categories);

        let imageUrls = [
            'https://asset.cloudinary.com/dbqvp70fu/9bb1282387d2e870bd764a7cbd36908f',
            'https://asset.cloudinary.com/dbqvp70fu/38d8ef5bc366f5a0906f982329bd6b18',
            'https://asset.cloudinary.com/dbqvp70fu/c5156be531cbbd2e1c1adf4258ab77d0'
        ]

        let products = [];

        for (let i = 0; i < 10; i+=1) {
            let newProduct = {
                name: faker.commerce.productName(),
                desciption: faker.commerce.productDescription(),
                price: faker.commerce.price(),
                category: _.sample(categories),
                imageUrl: _.sample(imageUrls)
            };
            products.push(newProduct);
        }
        await productsCollection.insertMany(products);

    } catch (e) {

        console.error(e);

    } finally {

        await connection.close();

    }
}

main();

Hello @Vimal_Kumar_G,

I tested your provided code, and it is working for me and inserts the data in the database, Just make sure you are executing the same send.js file, or check the package.json file all npms are updated to the latest version.

If you are new to node js and MongoDB then you have to check the free online courses at MongoDB university,

Hello @Vimal_Kumar_G,

There is no need for other js files, I just used your js file only.
