Setting up AppRTC (WebRTC) on Google App Engine

Question

I am not able to setup WebRTC on Google App Engine. Here are the steps that I performed to deploy the webrtc app on my Google App Engine Project.

Clone https://github.com/webrtc/apprtc on my local system.
Copied app.yaml from apprtc/src/app_engine/ to root folder of the local repository
Edited app.yaml [Set "application" to my appid "ckwebrtc" on Google App Engine]
npm install
grunt build
appcfg.py --oauth2 update

But I am getting "500 Server Error - The server encountered an error and could not complete your request".

URL - https://ckwebrtc.appspot.com/

Kindly help

Update: This is the error that I am getting:

You can close this window now.

What directory are you running the update command from? When you deploy, you need to specify the path to the app engine files, such as: <path to sdk>/appcfg.py --oauth2 update ./out/app_engine — Jeff Deskins
@JeffDeskins I tried to deploy the app using Google App Engine SDK and I am getting an error [I have updated my question and included the error generated during the deployment] — Rohit

I am not sure if this was a windows problem or not. I tried again from koding.com (Online Cloud) and was successful in setting up the app.

Here's how I did it.

$ git clone https://github.com/webrtc/apprtc.git

Edit app.yaml, package.json, mainfest.json etc with your application ID.

$ sudo npm install grunt-cli   
$ sudo npm install
$ sudo grunt build
$ sudo python /home/campuskarma/google_appengine/appcfg.py --oauth2 -A ckwebrtc update ./out/app_engine/

If you get an error asking for rollback then execute the following command:

$ sudo python /home/campuskarma/google_appengine/appcfg.py --oauth2 -A ckwebrtc rollback ./out/app_engine/      
$ sudo python /home/campuskarma/google_appengine/appcfg.py --oauth2 -A ckwebrtc update ./out/app_engine/

Each of the command mentioned here should be executed from the root of your application folder. (i.e. the folder where your application is cloned)
