You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: rollback_command.rb
    path of file: ./repos/jets/lib/jets/commands/rollback
    
    the code of the file until where you have to start completion: require "jets/commands/releases/releases_command"

module Jets::Command
  class RollbackCommand < Ba
    
    def run
      no_token_exit!
      Jets.boot
      payload = Release.new(@options).get(version)
      check_for_error_message!(payload)

      puts "Rolling back to version #{version}"
      # Download previous cfn templates
      Jets::Cfn::Download.new.download_templates(version)
      # Run cloudformation update
      Jets::Cfn::Ship.new(@options.merge(rollback_version: version)).run # also creates the Jets Api deployment record
    end
