Unable to publish rigid body markers

[echoGee]

Added the following to publish the individual markers.

  <!-- To publish the individual (unlabeled) markers along with the (labeled) markers of the rigid bodies -->
  <!-- keep pub_rigid_body to true to publish the markers of the rigidbody -->
  <arg name="pub_rigid_body_marker" default="true"/>  

But, I get the following error:

Were you managed to resolve the problem?
While publishing rigid body markers it is necessary to keep pub_rigid_body to true.
