Cannot run the navigation example with ros2 humble

Omniverse Isaac Sim
1

I tried to run the nav2 example through the tutorial(https://docs.omniverse.nvidia.com/isaacsim/latest/tutorial_ros2_navigation.html), but it didn’t show the results as the tutorial.
when I start rviz, I get errors:

and it doesn’t show the map image in rviz:

I use the navigation example with isaac sim 2022.2.1 and ros2-humble.

Are you getting messages in any of the mentioned topics?

|/tf|tf2_msgs/TFMessage|
|/odom|nav_msgs/Odometry|
|/map|nav_msgs/OccupancyGrid|
|/scan|sensor_msgs/LaserScan|

Try sourcing a terminal and doing ros2 topic echo /map

I tried it，and did’t get any message in /map, but I can get some message in /tf | /odom | /scan

Hi @mmmmark - Please try now this with the latest Isaac Sim release.

I have tried the Isaac Sim 2023.1.0, but when I open the navigation example scenes, I only see a car without any assets

Hi @mmmmark - Did you update the ROS before running the example? Running the new Isaac Sim ROS/ROS2 Bridge (Isaac Sim 2023.1.0 Release onwards) - #3 by scn
