Clojurians Log v2

hi, I'm a newbie and trying to use ring coercion to transform the type of a path parameter to int. I've written this code https://pastebin.com/J7LGiqgs following an example from https://cljdoc.org/d/metosin/reitit-ring/0.2.13/doc/ring/pluggable-coercion#full-example but I still can't see the value as int.

could anyone help me to understand how to troubleshoot this kind of issues? Thanks
