Hello,

This is an issue that occurs on headless Jetson NANO running Ubuntu 18.04 and ROS Eloquent.

Upon startup and connection via ssh terminal to the NANO followed by sourcing the ros eloquent setup file, the command ros2 node list returns the following output:

"//"

Introspection command like ros2 node info // returns:

"Failed to getsubscribernamesandtypes: node name must not be empty, result: 1, at /tmp/binarydeb/ros-eloquent-rcl-0.8.5/src/rcl/graph.c:62"

A consequence of this is that I cannot run rqt_reconfigure because the plugin cannot 'listparameters' of the node "//". Hence, the command `ros2 run rqtreconfigure rqt_reconfigure` freezes and needs to be killed manually.

If anyone has faced a similar issue of an 'empty' ros2 node automatically being launched, your help would be greatly appreciated!

Thanks in advance!
