JSON Question

Mongoose findOne function returns null/undefined

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 }));
