EEException: Server returned HTTP code: 404 --- testing app with Google App Engine and Google Earth Engine

Question

I am trying to test a basic app with Google App Engine using the trendy-lights example with Google Earth Engine App.

I cloned the trendy-lights app from the GEE github repository and updated the application name in app.yaml, EE_ACCOUNT in config.py and the privatekey.pem file. I didn't do any other change. However the trendy-lights app does not work.

Please see the error I got below. I am trying to figure out why it does not work. (Just FYI, I tried the sample flask app in GAE and it works well, I see the 'Hello World' text when I go to the app webpage).

Does anyone know what the error I got refers to? I have no clue and I don't know how to debug it.

Another question: For running this app (i.e., the trendy-lights example) using GAE and GEE, do I have to sign up for the GAE free trial? (I am a trusted tester for GEE)

Thanks for any help!

I am running osgeo Lubuntu on VirtualBox running on Windows 8.1. (VirtualBox-5.0.0-101573-Win, osgeo-live-8.5, Python 2.7.6, Google App Engine 1.9.24).

Answer 1

The issue posted in this question is solved now.

My service account had to be whitelisted by the administrators of the Google Earth Engine platform for the app to be able to run.
