Hi,

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/platform/turtlebot3/ros2_navigation2/) . Whenever I select the RViz '2D Nav Goal' and clicked on a location on the map, I have this error.

[rviz2-10] [INFO] [1610948935.827279512] [rviz2]: Setting goal pose: Frame:map, Position(4.61865, 0.885839, 0), Orientation(0, 0, 0.903558, 0.428465) = Angle: 2.25601 [btnavigator-7] [INFO] [1610948935.835065476] [btnavigator]: Begin navigating from current location to (4.62, 0.89) [btnavigator-7] [ERROR] [1610948935.876806873] [btnavigator]: Action server failed while executing action callback: "send_goal failed" [btnavigator-7] [WARN] [1610948935.877492238] [btnavigator]: [navigatetopose] [ActionServer] Aborting handle.

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.
