Mongoose findOne function returns null/undefined

Question

I always get

null

/

undefined

when fetching data from the database in my

/authenticate

route. Connection is successful and the user exists in the database (checked with Robo 3T). Here is an excerpt of the code:

var express = require("express");

var app = express();

var router = express.Router();

var mongoose = require("mongoose");

var user = require("../models/user");

var bodyParser = require("body-parser");

app.use(bodyParser.json());



router.post('/authenticate', function(req, res) {    

   user.findOne({ name: req.body.name }).then(function(foundUser) {

       if (!foundUser) { return res.status(404).send("No user matching name"); }

       return res.status(200).json(foundUser);

   });

});

Here is the request I'm executing from Postman:

Edited answer:

For express to parse form data in addition to json you need to add a second body parser to your application:

var app = require('express');
var bodyParser = require('body-parser');

// Enable express to parse body data from raw application/json data
app.use(bodyParser.json());

// Enables express to parse body data from x-www-form-encoded data
app.use(bodyParser.urlencoded({ extended: false }));
