Hi @Ruan,

I don’t think you’re finding it because send_data is an instance method not? and you are wanting to use it within a class method.

Try to remove the self of his method make_clone and in his task try something like:

clone_database = CloneDatabase.new
clone_database.response = ActionDispatch::Response.new
clone_database.make_clone
