heroku application error 503

I am new to Heroku and I am trying to deploy my first app onto Heroku. I followed instruction, which were:

  1. git init, add and commit my app's source code.
  2. heroku create to create Heroku remote repo for my app.
  3. git push heroku master to push my app's source code to heroku
  4. heroku open

Problem happened when I tried to run heroku open, which was:

$ heroku open
(node:6192) SyntaxError Plugin: 
ig.json: Unexpected string in JSON at position 72 module: 
task: runHook prerun
plugin: heroku
root: C:\Program Files\heroku\client
See more details with DEBUG=*

I checked file config.json at the direction as addressed above, and it was:

  "schema": 1,
  "install": "554c101b-d4de-496c-9768-710142ebfb20"
 "skipAnalytics": false

So what did I do wrong here?

I would be grateful for any help.

Thank you very much!

I had the same problem. Not sure why it ends up corrupted, but the config.json should look like the following (get rid of the curly brace before skipAnalytics):
