You don't have an image version called 'mobile' defined in your uploader.

If you've called your uploader ImageUploader, then open up app/uploaders/image_uploader.rb

Add the following version to the file:

  version :mobile do
    process resize_to_fill: [620, 270]
  end

Swap out the x and y sizes for whatever you need. After this all new images will have the 'mobile' attribute available. If you want it to apply to all old images, then you will need to save them and the new version will be available.
