Parse Server running locally returns "Unable to connect to the Parse API" when calling User signUp

[enjoyjeremy-bc]

Is there any reason I'm getting this error when running parse server locally, but not when hosted on Heroku? Status:100 Message:XMLHttpRequest failed: "Unable to connect to the Parse API"

I have mongodb installed and running locally. I also have a .env file that contains APP_ID and MASTER_KEY that gets pulled in with dotenv locally.

Here's an example of what I'm trying to do...

var express = require('express');
var bodyParser = require('body-parser');
var dotenv  = require('dotenv').config({silent: true});
var ParseServer = require('parse-server').ParseServer;
var Parse = require('parse/node');

// Set up the parse server
var databaseUri = process.env.DATABASE_URI || process.env.MONGOLAB_URI;
var api = new ParseServer({
  databaseURI: databaseUri || 'mongodb://localhost:27017/dev',
  cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
  appId: process.env.APP_ID || 'myAppId',
  masterKey: process.env.MASTER_KEY || ''
});

// Set up express
var app = express();
app.use(express.static(__dirname + '/public'));
var mountPath = process.env.PARSE_MOUNT || '/parse';
app.use(mountPath, api);
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
  extended: true
}));

// Initialize parse so that I can use in my routes and controllers
Parse.initialize(process.env.APP_ID,'unused');
Parse.serverURL = process.env.SERVER_URI || 'http://locahost:1337/parse';

// Routes
app.get('/', function(req, res) {
  res.status(200).send('[form goes here that sends POST to "/sign-up"]');
});
app.post('/sign-up', function(req, res) {
  var user = new Parse.User();
  user.set("email", req.body.inputEmail);
  user.set("password", req.body.inputPassword);

  user.signUp(null, {
    success: function(user) {
      res.status(200).send('Signup Success!');
    },
    error: function(user, error) {
      res.status(200).send('Signup Failed');
    }
  });
});

var port = process.env.PORT || 1337;
app.listen(port);

You need to set your server's url in the configuration of your server.

var api = new ParseServer({
  databaseURI: databaseUri || 'mongodb://localhost:27017/dev',
  cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
  appId: process.env.APP_ID || 'myAppId',
  masterKey: process.env.MASTER_KEY || '',
  serverURL: process.env.SERVER_URI || 'http://localhost:1337/parse' // add this line
});

Ah, thanks for catching that! That bonehead typo was part of the issue, but I also incorrectly assumed I needed to initialize the Parse SDK. Didn't realize that ParseServer takes care of that already.

serverURL: process.env.SERVER_URI || 'http://locahost:1337/parse' // add this line

There is a l missing in localhost within @drew-gross 's answer in case other has error with this.
