  Hello, please try removing the "viewer" instructions inside the red box that you highlighted and also the pink colored closing } bracket just outside of the bottom of the red box.  This information in the box about setting the resolution and FPS is not needed for a ROS launch as the launch file sets these values.

  You can set the resolution and FPS in the launch instruction of the the ROS2 wrapper with profile commands, which are the replacement for the stream width and height commands in the ROS1 wrapper.  For example, to set both depth and color to 848x480 and 15 FPS

   

  ros2 launch realsense2_camera rs_launch.py depth_module.depth_profile:=848x480x15 rgb_camera.color_profile:=848x480x15
