ROS2 BRIDGE test always fail Isaac sim

Hi I want to utilize ROS2 bridge.
But if loading ROS data, error msgs are detected as below.
And ROS2 bridge doesn’t work due to error.
Would you please advise me to resolve?

That’s why checked ROS2 BRIDGE working in test 2022.1.1
As a result is

For my verification, launch script doesn’t load parameter file.
So Carter’s position is unknown.

param_dir = LaunchConfiguration(
‘params_file’,
default=os.path.join(
get_package_share_directory(‘carter_navigation’), ‘params’, ‘carter_navigation_params.yaml’

because loading parameter manually, Rviz warning and error become normal status.

in the VSCODE debug LaunchDescription is one cause…?
