I made a simple Sinatra app to run a homepage. It's already working on my computer. Now I wanted to host it at heroku, but I can't manage it to make it run. I am not really familiar with concepts like "Gemfile" or "Procfile".
My ruby app requires Sinatra, haml and sinatra/r18n. My gemfile looks like this:
source :rubygems
gem 'sinatra'
gem 'thin'
gem 'sinatra-r18n'
gem 'haml'
My Procfile looks like this:
web: bundle exec ruby app.rb -p $PORT
My app.rb starts like this:
# app.rb
require 'rubygems'
require 'sinatra'
require 'sinatra/r18n'
require 'haml'
enable :sessions
helpers do
def set_lang (langcode)
...
Other files in the directory include the Gemfile.lock which was created through bundle install if I remember correctly and folders for "r18n", "public", "views".
If I start the application on heroku the "heroku ps" command says the application is "up" but if I use "heroku open" I get an "Internal Server Error".
Here is the "heroku logs" after I push it to heroku:

Has anybody an idea what's going wrong here? Maybe something obvious if you are more familiar to the used concepts. I also would take hints for material that helps me to solve the problem, but until now all my googling/reading didn't help.
Update 28-09 I now removed the Procfile from code and still get the "Internal Server Error". Here is some more log which should include the crash:
