Asset_Sync not pushing to S3 - ruby-on-rails-4

Question

I am building a rails app on heroku, and want to deploy the js, css, and image files to a bucket on Amazon. I haven't found many resources for this, but I am using this (2012) tutorial for guidance; https://firmhouse.com/blog/complete-guide-to-serving-your-rails-assets-over-s3-with-asset_sync
The site is mainly css and js at the moment. Here is my code so far;
production.rb
Rails.application.configure do
config.action_controller.asset_host = "http://localize.s3.amazonaws.com"
config.cache_classes = true
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
config.serve_static_assets = false
config.assets.compress = true
config.assets.compile = false
config.assets.digest = true
end
initializers/asset_sync.rb
if defined?(AssetSync)
AssetSync.configure do |config|
config.fog_provider = ENV['FOG_PROVIDER']
config.aws_access_key_id = ENV['AWS_ACCESS_KEY_ID']
config.aws_secret_access_key = ENV['AWS_SECRET_ACCESS_KEY']
config.fog_directory = ENV['FOG_DIRECTORY']
config.fog_region = ENV['FOG_REGION']
# Don't delete files from the store
config.existing_remote_files = "delete"
# Automatically replace files with their equivalent gzip compressed version
config.gzip_compression = true
# Use the Rails generated 'manifest.yml' file to produce the list of files to
# upload instead of searching the assets directory.
config.manifest = true
config.custom_headers = { '.*' => { cache_control: 'max-age=31536000', expires: 1.year.from_now.httpdate } }
end
end
Heroku Vars
AWS_ACCESS_KEY_ID: *****************
AWS_SECRET_ACCESS_KEY: *****************************
FOG_DIRECTORY: localize
FOG_PROVIDER: AWS
FOG_REGION: us-west-2
gemfile
gem 'rails', '4.1.1'
gem 'uglifier', '>= 1.3.0'
gem 'jquery-rails'
gem 'sdoc', '~> 0.4.0', group: :doc
#aws
gem "fog", "~>1.20"
gem 'asset_sync'
group :development do
gem 'thin'
end
group :production do
gem 'newrelic_rpm'
gem 'rails_12factor'
gem 'pg'
end
I also ran:
heroku config:add FOG_PROVIDER=AWS AWS_ACCESS_KEY_ID=xxx AWS_SECRET_ACCESS_KEY=yyy
Along with
heroku config:add FOG_DIRECTORY=localize
And then when I run
bundle exec rake assets:precompile
Or
RAILS_ENV=production bundle exec rake assets:precompile
I get this output;
rake aborted!
AssetSync::Config::Invalid: Fog directory can't be blank, Aws access key can't be blank, Aws secret access key can't be blank
Anyone who has experience with rails, heroku, and S3 who could guide me in the right direction would be much appreciated. Thanks in advance.

Ok looking at your settings there seems to be a few things wrong, Ill add what i normally use and hopefully it will help you
Production.rb
ExampleApp::Application.configure do
config.action_controller.asset_host = "http://exampleapp.s3.amazonaws.com"
config.cache_classes = true
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
config.serve_static_assets = true
config.assets.compress = true
config.assets.compile = true
config.assets.digest = true
end
asset_sync.rb
if defined?(AssetSync)
AssetSync.configure do |config|
config.fog_provider = ENV['FOG_PROVIDER']
config.aws_access_key_id = ENV['AWS_ACCESS_KEY_ID']
config.aws_secret_access_key = ENV['AWS_SECRET_ACCESS_KEY']
config.fog_directory = ENV['FOG_DIRECTORY']
config.fog_region = ENV['FOG_REGION']
# Don't delete files from the store
config.existing_remote_files = "delete"
# Automatically replace files with their equivalent gzip compressed version
config.gzip_compression = true
# Use the Rails generated 'manifest.yml' file to produce the list of files to
# upload instead of searching the assets directory.
config.manifest = true
config.custom_headers = { '.*' => { cache_control: 'max-age=31536000', expires: 1.year.from_now.httpdate } }
end
end
