Moveit Perception pipeline from a real-world camera

edit

I've been trying to generate Octomap surface from a real-world Intel Realsense camera following the tutorial for sim based setup - https://ros-planning.github.io/moveit.... The simulated example works properly as described in the tutorial. To change the setup to real-world I've updated the point cloud topic in sensors_kinect_pointcloud.yaml to the camera's point topic. However, Rviz doesn't generate Octomap surfaces from camera point cloud stream. I've verified the point cloud stream is working properly by visualising in Rviz using Point cloud plugin. I'm using ROS Noetic in my setup. Thank you for any support with this question.
