I've been trying to deploy my AngularFullstack (node) app to Heroku. I created the app in the terminal with: yo angular-fullstack. Whenever I try to deploy to Heroku I get the following when I go to my deployed app:
Application Error
An error occurred in the application and your page could not be served. Please try again in a few moments.
If you are the application owner, check your logs for details.
The logs are:

At first I thought it was a problem with my favicon but after moving it around and tinkering with a number of server/config files I tried uploading a different AngularFullstack app that I already successfully put on Heroku. When I tried to reupload it, it produces the exact same error even though I can update it on its own Heroku app. I also tried creating other Heroku apps in case the one in question was corrupted but I still get the same error. This makes me think it is something wrong with the way I'm trying to upload to Heroku.
With this in mind, here are the steps that I'm trying to deploy to Heroku:
$ cd dir$ heroku login$ heroku git:remote -a nameOfApp$ git init$ git add .$ git add -A$ git commit -m "doesntMatter"$ git push -f heroku

Here are the steps that I'm trying to deploy to Heroku: 1) $ cd dir 2) $ heroku login 3) $ heroku git:remote -a nameOfApp 4) $ git init 5) $ git add . 6) $ git add -A 7) $ git commit -m "doesntMatter" 8) $ git push -f heroku
Don't do that!
To push a Yeoman stack to Heroku, you must do:
grunt build
grunt buildcontrol:heroku
From then on:
- You will avoid the kind of mistake you just had.
- If anything, you will be able to see at which step it is failing.
If that still doesn't help, you might want to look at this:
is your favicon file readable? For some reasons, the image minimizer from grunt might have break it when grunt wasn't launched as expected. If it isn't, change it and also check whether the other image files in your app are readable.
