Visit [Airbrake error](https://herokuapp16263207herokucom.airbrake.io/projects/122010/groups/3328076902073738874?tab=notice-detail) to view the full backtrace.

Start with the failing `/click_through/go` URL and search the Rails routes and controller definitions for the missing `ClickThroughsController`. Reproduce the request if possible and determine which existing entry point should handle it; done means the URL no longer raises the reported routing error.
