Hi @muthukumar1
Thank you for your detailed post. We are working to fix the issue with the Realsense camera and make a fix soon.
I keep you posted when it will be released.
The issue with the realsense camera is currently related to a new ROS 2 package that exposes new types of topics and services, which do not match with the demo.
