I am trying to add a new field to the Path.msg. I am using ros rolling release, overriding the nav_msgs package and using the nav2 main branch. My OS Version is Ubuntu 20.04.4 LTS.

Terminal 1: source /opt/ros/rolling/setup.bash colcon build -packages-select nav_msgs (with the changes to the Path.msg)

Terminal 2: source overlay_ws/install/setup.bash cd nav2_ws colcon build

Terminal 3: source nav2_ws/install/setup.bash Launch the nav2 sim without rviz

Terminal 4: source nav2_ws/install/setup.bash send initial pose send navigate to pose action

At this point I get the error:

recvUC: malformed packet received from vendor 1.16 state parse:data <52545053 02010110 011028d7 47037a6e b71fa3f1 09010800 0ffd7662 30d11f17 @0x20 15051400 00001000 00000000 03960000 00000000 01000000 07011c00 00000000> (note: maybe partially bswap'd) {{15,5,20},0,16,0,9603,1}
