p318/9 Unable to get demo working

[threent2]

The model loads OK but the terminal continues to loop showing :

[gazebo-5] [WARN] [1759333844.969642783] [controller_manager]: No clock received, using time argument instead! Check your node's clock configuration (use_sim_time parameter) and if a valid clock source is available

even after the use_sim_time is set to true

The demo window shows the expected input screen but even choosing "random valid" as the start and goal states, the movement fails on execution even though it passes planning and the terminal loops on

[ros2_control_node-5] [WARN] [1759334096.053364711] [controller_manager]: Waiting for data on 'robot_description' topic to finish initialization
