ros2 topic /initialpose doesn't echo
I am working on Ubuntu 18.04 ROS2 dashing. The command: "ros2 topic echo /initialpose" answers:
$ ros2 topic echo /initialpose
Cannot echo topic '/initialpose', as it contains more than one type: [geometry_msgs/msg/PoseWithCovarianceStamped, std_msgs/msg/String]
Don't know what to do. It seems that I am the only one with this problem since I didn't find any issue open on that...
