I know this might be a possible duplicate of this, but the answer there does not help. I'm using ROS2 Foxy on Ubuntu focal

I'm using the Linorobot2 to try navigating a custom robot. After running gazebo, navigation (calls nav2_bringup/launch/bringup_launch.py), and rviz. Immediately, I get the following error:

 [rviz2-1] [INFO] [1645.956] [rviz2]: Message Filter dropping message: frame 'odom' at time 1645.930 for reason 'Unknown'

Navigation still works for a while, maybe 2 or 3 minutes and then the following error occurs as well:

 [rviz2-1] [INFO] [1645.956] [rviz2]: Message Filter dropping message: frame 'odom' at time 1645.930 for reason 'Unknown'

Then the robot in rviz stops following the path, but will pop up at the right location after a while. Any ideas as to how to fix this?
