Rails 4 - Assets routing error

Question

I am transitioning from Heroku to AWS Elastic Beanstalk and in my logs I keep seeing this error with .css and .js assets.

Rails 4.2 Ruby 2.2.5

ActionController::RoutingError (No route matches [GET] "/assets/application-be8de4c1a8d12cb784028972b73fe7e23d4acc55757e3d297ef5e3db4161c369.css"):

Could it be that your configuration file is telling EB to skip asset compilation? See docs here: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_Ruby.container.html#create_deploy_Ruby.env.console.ruby.envprops
