Service call /lifecycle_manager/manage_nodes not responsive

In ROS2 Navigation course, Unit 2
When I’m trying to give this command:
ros2 service call /lifecycle_manager/manage_nodes nav2_msgs/srv/ManageLifecycleNodes "{command: 2}"

The output what I get is: requester:
making request: nav2_msgs.srv.ManageLifecycleNodes_Request(command=2)

I am not able to receive any response. Please let me know how to figure this out.

Hi, I think you might want to use ros2 lifecycle set instead of calling a service. Can you see if that works?
