node.js - Google App Engine 502 (Bad Gateway) with NodeJS

Question

I have a full web application using NodeJS, MongoDB (Mongoose as the driver) and ExpressJS.

The project works perfectly on my local machine. Today I decided to move everything to production. I'm using Google App Engine to host my application, and Compose (formally MongoHQ) to host my database.

App Engine servers my application perfectly, although my API does not seem to work. My API is served from example.com/api, and each request (GET, POST, DELETE and PUT) all returns a 502 (Bad Gateway) error.

I tried running my application on my local machine while connected to my remote MongoDB database and that worked perfectly fine. So it must be a problem with App Engine or NodeJS, not with MongoDB.

I have tried checking all error logs within Google Cloud, although there are no errors.

Why is App Engine/NodeJS serving my application's static content perfectly fine, although not allowing any requests to my API?
