For some more context: We have an app where with a

get '/:username' => "…"

route which was raising a second exception to an obscure status code route.

I highly recommend anyone who needs to render errors this way either use controller exception catching or bypass the rails router all together.

This is a much better way to do this

config.exceptions_app = proc{|env|
  ErrorsController.action(:render_error).call(env)
}
