Google Cloud Platform App Deployment Resulted in 502 Server Error

Question

After making sure that my RESTful API works fine locally, I followed the instructions in the following guide to deploy it: https://cloud.google.com/nodejs/getting-started/hello-world

... and I believe I did it right. I got the following screen after gcloud app deploy finished running.

Sadly, https://_project-id.appspot.com (or gcloud app browse on the command line) keeps leading to a 502 Server Error:

Error: Server Error

The server encountered a temporary error and could not complete your request. Please try again in 30 seconds.

(and yes, I tried again multiple times)

======================================================== Edit: When I checked the Deployment Manager, it says: You don't have any deployments yet.

What would be the problem here?

Last part of server.js

// Listen
app.listen(80);

Any ideas what I should do? Thank you very much in advance.

@Zachary It just repeats: [email protected] start /app node server.js (like in the picture above) — TravelingAries
Any chance that the app is not actually listening, or has died? — jarmod
@jarmod It was listening fine locally.. This is my first time trying to deploy something and I have no idea what the problem is — TravelingAries

As for this problem, I just restructured everything. You can see the files here: https://github.com/edwardjhchang/Jjalkey-Kakao-Talk-Plus-Friend-Auto-Reply-API

Most of all, you must create var http = require('http'); (which I did not realize initially). Check my repository for more details :D
