Spam from the controller_server/LifecyclePublisher
Hey!
I'm looking at navigation2 to drive around with a differential robot and it works so far quite nice, but the LifecyclePublisher is spamming:
[controller_server-3] [WARN] [1605637131.711642756] [LifecyclePublisher]: Trying to publish message on the topic '/local_costmap/clearing_endpoints', but the publisher is not activated
I'm using (mainly) the default parameters, so I have no idea where I should look at to fix it. What is this node doing and which parameters are relevant here?
