view_robot.launch.py does not update to joint states

[patrickwasp]

ros version: humble

running ros2 launch kortex_description view_robot.launch.py and pressing on "Randomize" in the "Joint State Publisher" window does not reliably update the arm positions. The terminal will say

[joint_state_publisher_gui-3] [INFO] [1696086847.268803477] [joint_state_publisher_gui]: Randomizing

but the robot remains upright. Quitting (ctrl+c) and rerunning ros2 launch kortex_description view_robot.launch.py occasionally works. I cannot reliably replicate when it works or doesn't.

Could it be possible the randomization tries to move the arm in a configuration outside its joint limits?

No, that was just an example but trying to move any joint results in no motion.
