Introduction to ROS2-Navigation: Rviz not working

Hello community,

I am trying to launch the example in chapter one. However, it seems like the Rviz is not working correctly.

The turtle bot is not showing on the Rviz, and there are a lot of error messages that continue to pop out on the console.

It is my first time learning nav2, so I do not know where should I debug from.
Please let me know if I missed something.

You have to provide the initial pose of the robot in RViz using the 2D Pose Estimate tool, as indicated in the notebook:
