Wrong assets pipeline URL at production

Hello G.s!

I’m new with RoR and I having problems to deploy my app using AWS
Elastic
Beanstalk and Cloundfront CDN. The problem is with the assets url at
production. The url to css at index page, for example, should look like
this:
http://xxx.cloudfront.net/assets/application-133f6d0c28cff54b4ad2a9a23a90a72b.css
But
when I deploy the app, the page is requesting the file at:
http://xxx.cloudfront.net/stylesheets/application.css Does any one knows
how to solve this?

Thank you.

Felipe Coutinho.
