Move_base problem: "Unable to get starting pose of robot, unable to create global plan"

Greetings,

I'm trying to configure move_base on a Jetson Nano board (Ubuntu 18.04, ROS Melodic) equipped with a ZED2 camera. The ZED2 provides the "/odom" topic which updates the robot pose. The package seems to work well and avoids obstacles perfectly well.

Unfortunately though, I frequently get this bug: "Unable to get starting pose of robot, unable to create global plan", and thus the whole system breaks and stops. Not sure if it's a computation or memory problem - but checked for both and it doesn't seem that I hit any limitations.

I am following the tutorial on this page: move_base - ROS Wiki

Here are the config files for move_base on the jetbot:
