MongoDB Not Sending Responses Through Postman? - node.js

Question

Oh man, this API project is a real huge pain. I got all of these endpoints working yesterday, but as soon as I stared trying to add data to a collection in the database (via Mongo shell), all of a sudden my requests are hanging up. Here is my server:
var express = require('express'),
app = express(),
port = process.env.PORT || 3000;
mongoose = require('mongoose'),
Character = require('./api/models/characterListModels'),
bodyParser = require('body-parser');
mongoose.Promise = global.Promise;
mongoose.connect({ useNewUrlParser: true }, 'mongodb://127.0.0.1:27017/streetfighterdb');
app.use(bodyParser.urlencoded({ extended: true}));
app.use(bodyParser.json());
var routes = require('./api/routes/characterListRoutes')
routes(app);
app.listen(port);
console.log('Street Fighter RESTful API server started on: ' + port);
Here is my controller
'use strict';
var mongoose = require('mongoose'),
Character = mongoose.model('Characters')
exports.list_all_characters = function (req, res) {
Character.find({}, function (error, character) {
if (error) {
res.send(error);
} else {
res.json(character)
}
})
}
exports.create_a_character = function (req, res) {
var new_character = new Character(req.body);
new_character.save(function (error, character) {
if (error) {
res.send(error);
}
res.json(character);
});
}
exports.get_a_character = function (req, res) {
Character.findById(req.params.characterId, function (error, character) {
if (error) {
res.send(error);
}
res.json(character);
});
}
exports.update_a_character = function (req, res) {
Character.findByIdAndUpdate({
_id: req.params.characterId
}, req.body, {
new: true
}, function (error, character) {
if (error) {
res.send(error);
}
res.json(character);
});
}
exports.delete_a_character = function (req, res) {
Character.deleteOne({
_id: req.params.characterId
}, function (error, character) {
if (error) {
res.send(error);
}
if (!error) {
res.json('Character Successfully Deleted');
}
})
}
Here is my router
'use strict';
module.exports = function(app) {
var characterList = require('../controllers/characterListController');
app.route('/characters')
.get(characterList.list_all_characters)
.post(characterList.create_a_character);
app.route('/characters/:characterId')
.get(characterList.get_a_character)
.put(characterList.update_a_character)
.delete(characterList.delete_a_character);
};
Here is my Model
'use strict';
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var characterSchema = new Schema({
name: {
type: String,
required: true,
}
})
module.exports = mongoose.model('Characters', characterSchema);
Now I have tried a few things.
Removed the specific response and just added a generic res.send('success') and it worked.
I also replaced the {} in the Character.find() method with a [] and it worked (responded with an empty object). For some reason though, none of the other endpoints return responses.
Added a console.log(res) and a console.log(req) and got the logs in the console.
What is going on here? Help!!

Answer 1

Referenced by mongoose offical docs
mongoose.connect('mongodb://username:password#host:port/database?options...', {useNewUrlParser: true});
You are passing the options as first argument, please replace it as offical docs example.

Answer 2

Ok, this is ridiculous, but it turns out that passing the { useNewUrlParser: true } broke it.
