I am trying to run navigation example for both simulated Adlink neuronbot (https://github.com/Adlink-ROS/neuronbot2) and turtlebot3 (https://emanual.robotis.com/docs/en/p...) . Whenever I select the RViz '2D Nav Goal' and clicked on a location on the map, I have this error.

After I got this error message, the bt_navigator will crash and I will need to relaunch it.

After attempting for a few times, I managed to get the navigation function properly without any changes made but the error occurred again when I tried to navigate again. For now I could not identify what might be the cause and the pattern seems quite random for me, any advice on how I could troubleshoot this issue or narrow down the possibilities?

Additional Information,

  1. I am running Gazebo simulation and teleop seems to be working properly for both Adlink neuronbot and turtlebot3.
  2. I am using Virtualbox running Ubuntu Focal (20.04) and installed ROS2 Foxy via Debian Packages.

Thank you.
