Getting an Error While Setting Up a Parse Server on AWS

I have been trying to figure this out for the last several weeks and I tried everything but with no avail. If somebody could PLEASE give me some suggestions on how to make this work, that would mean soooooo much.

This is my problem:

I am following this blog: https://mobile.awsblog.com/post/TxCD57GZLM2JR/How-to-set-up-Parse-Server-on-AWS-using-AWS-Elastic-Beanstalk. I think I followed all the steps correctly but I am not seeing my object being upload to Mongo.

Here is what I've done so far:

On my Parse dashboard, I copied my Application ID:

To my AWS software configuration:

Then, I copied the Application ID and put it in my AppDelegate.swift like so:

ParseMutableClientConfiguration.applicationId = "applicationId"

Then, on my Parse dashboard, I copied my master key:

Then, I copied it to the property value on my AWS software configuration:

Then, I copied the Master Key and put it in my AppDelegate.swift like so:

`ParseMutableClientConfiguration.clientKey = "my master key"'.

Then, I copied my MongDB URI, including my own account and password:

And put it in my AWS software configuration

Then, I copied the URL on top my AWS dashboard and put it in my AppDelegate.swift like so:

ParseMutableClientConfiguration.server = "myServerURL/parse".

Here's the problem: When I run this code:

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    let testObject = PFObject(className: "TestObject")
    testObject["foo"] = "bar"
    testObject.saveInBackgroundWithBlock { (success, error) -> Void in
        print("Object has been saved.")
    }
}

I get this error: 2016-04-03 15:32:19.113 ParseStarterProject-Swift[15395:161311] [Error]: {"code":1,"message":"Internal server error."} (Code: 1, Version: 1.12.0) Though, it says Object has been saved, the object is not showing up on Mongo. Thank you in advance for your help!
