General
I've removed
[]()
from the end here:using CallbackReturn = rclcpp_lifecycle::node_interfaces::LifecycleNodeInterface::CallbackReturn;[]()
I don't think that's a valid C++ syntax (sorry, I'm a beginner in C++). Also, because the actual code doesn't have
[]()
(This change can be backported to Humble & Iron)
