This is the model of the product, where i have the mongoose schema of the object.

const mongoose = require('mongoose');

const productSchema = mongoose.Schema({

    _id: mongoose.Schema.Types.ObjectId,

    name: String,

    price: Number

});

module.exports = mongoose.model('Product', productSchema);

This is my method POST.

const express = require("express");

const router = express.Router();

const mongoose = require("mongoose");



const Product = require("../models/product");





      router.post("/", (req, res, next) => {

          const product = new Product({

            _id: new mongoose.Types.ObjectId(),

            name: req.body.name,

            price: req.body.price

          });

          product

            .save()

            .then(result => {

              console.log(result);

              res.status(201).json({

                message: "Handling POST requests to /products",

                createdProduct: result

              });

            })

            .catch(err => {

              console.log(err);

              res.status(500).json({

                error: err

              });

            });

        });

The problem is the following: whenever i call the method POST on POSTMAN the server never respondes, it gives the error 500 on visual studio code and the server crashes. The body used in POSTMAN is correct and also the connection to the mongoDB is successful.

The server prints the following error:

(node:3214) UnhandledPromiseRejectionWarning: MongoNetworkError: failed to connect to server [node-rest-shop-shard-00-00-pbcph.azure.mongodb.net:27017] on first connect [MongoNetworkError: connection 4 to node-rest-shop-shard-00-00-pbcph.azure.mongodb.net:27017 timed out]

(node:3214) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)

i think your problem it may that yo don't exporting the router

   var express = require('express');



var Product = require('../models/product');



const router = express.Router();

const mongoose = require('mongoose');



router.post('/product', (req, res) => {



    const product = new Product({

        _id: new mongoose.Types.ObjectId(),

        name: req.body.name,

        price: req.body.price

      });

      product

        .save()

        .then(result => {

          console.log(result);

          res.status(201).json({

            message: "Handling POST requests to /products",

            createdProduct: result

          });

        })

        .catch(err => {

          console.log(err);

          res.status(500).json({

            error: err

          });

        });



});





module.exports = router;

Try this code i test it in postman.

Post product
