Hello @Ruan,

I think you're not finding why send_data is an instance method, right? and you're wanting to use it within a class method.

Try to remove self from your make_clone method and in your task try something like:

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