depthimage_to_laserscan package didn't work with rs_d400_and_t265_launch.py

Hi ! I wanted to use depthimagetolaserscan package with rsd400andt265launch.py on my realsense cameras(d435 and t265). But it didn't work at all.

Interestingly, this package somehow worked with rs_launch.py, so I guess that is the problem about topic.....

I'm not used to ROS2 very much and I don't know how to deal with this problem.
