I want to be able to see in the better-error exception page the full stack trace to the method which contains the error.
After I move the helper file to a gem and use this gem in my app, if an error occurs the better-error gem cannot show in the exception page the details inside the gem code and shows the method in my app which calls the first method in the gem.
In this way I cannot easily debug the code inside the gem file.
In general, what is the proposed way in debugging code that exists in a gem (or engine)?
