try to change:
<Route Url="/{id:[0-9]+}" Method="GET" Call="NewsGetItem"/>

try to open developer tools (shift-ctrl-P) then search for "developer tools" - check in console if there are any errors 

on any class that extends  Ens.Request or Ens.Response you may use:

Parameter COMPRESS = 2;
Property JSON As %Stream.GblChrCompress;

On large messages (or in a system with billions of messages per day) the save on storge is huge!
- Visual trace working fine
- You may search within the compressed property (but it will take time)
- Property is visible in SQL queries against Ens.MessageHeader / Ens.MessageBody 
- The "out of the box" purge working fine
