When attempting to deploy to Heroku ArgumentError: Missing required arguments: aws_access_key_id, aws_secret_access_key

Question

There seems to be a lot of issue lately with people running into this issue and I have done my best to solve it through solutions on other queries related to this problem.

 # config/initializers/carrierwave.rb
if Rails.env.production? || Rails.env.development?
  CarrierWave.configure do |config|
    config.fog_credentials = {
      :provider               => 'AWS',                        # required
      :aws_access_key_id      => ENV['S3_ACCESS_KEY_ID'],                        # required
      :aws_secret_access_key  => ENV['S3_SECRET_ACCESS_KEY'],                        # required
      :region                 => 'us-east-2'                  # optional, defaults to 'us-east-1'
    }
    config.fog_directory  = 'cameronrailsbucket'                     # required
    config.fog_attributes = {'Cache-Control'=>'max-age=315576000'}  # optional, defaults to {}
    config.storage = :fog
  end
end

Heroku config is set like this:

S3_ACCESS_KEY_ID:         <ACCESS CODE>
S3_BUCKET:                cameronrailsbucket
S3_REGION:                us-east-2
S3_SECRET_ACCESS_KEY:     <SECRET CODE>

Make sure you have rake and rails environment to production over Heroku

heroku config
RACK_ENV:              production
RAILS_ENV:             production
