Run isaac_ros_examples.launch.py ​​and ESS rosbag in the failed document

[jjiszjj]

Terminal 1 runs ``` ros2 launch isaac_ros_examples isaac_ros_examples.launch.py ​​launch_fragments:=ess_disparity \ engine_file_path:=${ISAAC_ROS_WS:?}/isaac_ros_assets/models/dnn_stereo_disparity/dnn_stereo_disparity_v4.0.0/ess.engine \ threshold:=0.0

Terminal 2 runs ```
ros2 bag play -l ${ISAAC_ROS_WS}/isaac_ros_assets/isaac_ros_ess/rosbags/ess_rosbag \
--remap /left/camera_info:=/left/camera_info_rect /right/camera_info:=/right/camera_info_rect.

Terminal 1 will report an error, I don't know how to solve it. If anyone encounters the same problem, please tell me how to solve it. Thank you
