2020-12-18 12:47:46 -0500 marked best answer rosrun depthimage_to_laserscan not working

I am using turtlebot 2 with astra pro sensor on ubuntu 14 with ros indigo. when i run

$rosrun depthimage_to_laserscan depthimage_to_laserscan image:=camera/depth/image_raw

i get no response or any output window, whereas i can easily get rgb, ir and depth images using rosrun commands. can anybody help if there is needed some extra configuration in order to make it work?
