Exception while calling service of node '<my_node>' : None

edit

When running navigation2 and then calling ros2 param list, I get following errors:

• Exception while calling service of node '/bt_navigator_rclcpp_node': None
• Exception while calling service of node '/controller_server': None
• Exception while calling service of node '/global_costmap_client': None
• Exception while calling service of node '/lifecycle_manager_navigation': None
• Exception while calling service of node '/local_costmap_client': None
• Exception while calling service of node '/waypoint_follower_rclcpp_node': None

How to reproduce

1. Copy the foxy navigation 2 launch file into own workspace
2. Run with the default param file

Environment

• foxy (0.9.2-1focal.20211119.123452)
• Ubuntu 20.04
