Hello, 

i saw a transformation on PUA_JSON module about json.parse transformation. i think it is missing on cookbook transformation.

Kind regards

...
event_route[xhttp:request] {
        $var(call-id) = $(rb{json.parse,Call-ID});
        if ($(rb{json.parse,Event-Package}) == "dialog") {
                xlog("L_INFO", "$var(call-id)|log|received $(rb{json.parse,Event
-Package}) update for $(rb{json.parse,From})");
                pua_json_publish($rb);
        }
}
