Local Traffic Policy (12.1.x), log action and tcl commands

Hi,

 

I am trying to use tcl commands in message for log action. I tried tcl:[HTTP::uri] as well as "tcl:[HTTP::uri]" but all I am getting is logging text instead URI like:

 

This is tcl:[HTTP::uri]

 

instead of

 

This is /index.html

 

Question is if this is bug or tcl commands can't be used in log action?
