Issue details

When i run the moveit support package for this driver through:
ros2 launch ur_moveit_config ur_moveit.launch.py ur_type:=ur5 launch_rviz:=true
i get this warning
[WARN] [1731009987.767804840] [moveit_ros.robot_model_loader]: No kinematics plugins defined. Fill and load kinematics.yaml!
However this is not a problem when controlling the robot through the rviz gui using moveit.
The problem arises when im trying to run my own move_group node in parallel with the ur_moveit_config package. i get this error when trying to use Inverse kinematics for setting joint value targets from poses in cartesian space.
[ERROR] [1731009989.969819875] [moveit_robot_state.robot_state]: No kinematics solver instantiated for group 'ur_manipulator'
I used the move group interface tutorial to build my custom node.
These are the changes i made to the ur_moveit.launch.py:

i added this code to the launch_setup in ur_moveit.launch.py

end_effector_node_2 = Node(
    package='moving_ur5', 
    executable='move_group_reciever', 
    output='screen',
    parameters=[
        robot_description,
        robot_description_semantic,
        publish_robot_description_semantic,
        robot_description_kinematics,
        robot_description_planning,
        ompl_planning_pipeline_config,

        planning_scene_monitor_parameters,

everything runs well until this line

move_group.setJointValueTarget(target_pose1);

Here i get the error as described above.

No kinematics plugins defined. Fill and load kinematics.yaml! in the standard configuration often points to a problem with locale. What is your output for the locale command?

If you are using a locale (LC_NUMERIC specifically) that uses "," as a decimal separator, things break. As a workaround you can try starting things using

LC_ALL=C ros2 launch ur_moveit_config ur_moveit.launch.py ur_type:=ur5

I hope that helps.
