Hello all,

Just a quick error since I compile the navigation stack from source, I just update the plugins inside the nav2_bt_navigator without touching the node source.

Here is the error I got

[bt_navigator-14] [INFO] [1642690335.156322425] [bt_navigator]: Configuring [bt_navigator-14] [bt_navigator-14] >>> [rcutils|error_handling.c:108] rcutils_set_error_state() [bt_navigator-14] This error state is being overwritten: [bt_navigator-14] [bt_navigator-14] 'invalid empty action name, at /tmp/binarydeb/ros-foxy-rcl-action-1.1.11/src/rcl_action/names.c:36' [bt_navigator-14] [bt_navigator-14] with this new error message: [bt_navigator-14] [bt_navigator-14]

Thanks for your advice I try to load a simple xml and it didn't crash and it didn't display anything also, is it a correct start ?

Yes I believe that's correct as far as I know, but I am new to nav2.

Seems to be the behavior tree the issue but it has no meaningful logs telling what it doesn't like
