what I used is Ubuntu 18.04 with ros2 dashing。When I use ISAAC SIM nvblox with realsense, the error occurs and has depth frames but no rgb frames

hello,
I have meet the same error. in tutorial-realsense
when I run
“cd /workspaces/isaac_ros-dev/ &&
rosdep install -i -r --from-paths src --rosdistro humble -y --skip-keys “libopencv-dev libopencv-contrib-dev libopencv-imgproc-dev python-opencv python3-opencv nvblox””

I get error:
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
realsense2_description: No definition of [xacro] for OS version [focal]
realsense2_camera: No definition of [librealsense2] for OS version [focal]

I use AGX xavier, ubuntu20.04, jetpack5.1.1, realsense D455,

“isaac_ros_nvblox quickstart demo” alone work well ,
“isacc ROS realsense setup” alone work well.

combine this two project together, meet this error.

how to solve this ?

Thanks, Tom
