unable to set dynamic uri in request of netty4-http component in camel

I am trying to call an external service with some dynamic uri which will be comming in request e.g www.abc.com/

{id} i get that id in ${header.id} which is perfectly log in console but when i am trying to use netty4-http component in camel i used same dynamic uri in path of configuration but i am getting error of 404 not found because the url is not properly made.

It is not using simple expression language like "${header.id}" or any placeholder like "id" and also not work with this "{id}

"
I am using blue print dsl in redhat code ready studio 12.11.0 GA

The main problem is how to use dynamic uri with netty4-http component in camel.
