Ruby 2.3.1
Rails 5.1.2
Been trying to deploy my rails app into heroku by setting its multi buildpack (heroku buildpacks:set https://github.com/heroku/heroku-buildpack-multi.git) with https://github.com/heroku/heroku-buildpack-ruby.git and https://github.com/heroku/heroku-buildpack-nginx.git. When I git push heroku master, it successfully uploads the repo into heroku. When I try to go into the website, I get the application error page. So I go and check heroku logs and I see the following error:
Starting process with command `bin/start-nginx bundle exec unicorn -c config/unicorn.rb`

Plus I get a constant loop with the following message:

Which I would assume its because it trying to start with the Procfile:

---ANSWER---
Needed to add $PORT into my Procfile.
web: bin/start-nginx bundle exec unicorn -p $PORT -c config/unicorn.rb
How to get rid of the argument error:
Best guess is that the empty pids folder wasn't cloned correctly when you pushed it to Heroku using git push heroku.
So what I would do is first check and see if it exists and if not, create it using mkdir pids.
How to get rid of the infinite loop issue
Forgot to add
$PORTinside Procfile
