xmlrpc.client.Fault: <Fault 1: "<class 'RuntimeError'>:!rclpy.ok()"> about rclpy HOT 5 CLOSED

have you sourced the setup.bash file, if not please source it using source /opt/ros/humble/setup.bash

from rclpy.

I have source file loaded.

from rclpy.

according to the stack, it looks like client receives the Fault from the server. can you restart the daemon to see if anything changes?

root@tomoyafujita:~/ros2_ws/colcon_ws# ros2 daemon stop
The daemon is not running
root@tomoyafujita:~/ros2_ws/colcon_ws# ros2 daemon start
The daemon has been started
root@tomoyafujita:~/ros2_ws/colcon_ws# ros2 daemon status
The daemon is running

Hi @fujitatomoya ,

With restart daemon, this issue is not reproduced now.

from rclpy.

@ionutnechita-intel thanks for checking. i will go ahead to close this for now. please reopen or create another if you meet the problem. i think we need to keep the reproducible environment to debug the ros2 daemon process in next time.
