Thank you for your post, and welcome to the Isaac ROS forum.
From your attached log, the process “ros2-2” for reading the rosbag finished too early. I suspect that the file might be broken. Could you try deleting the rosbag and following the quickstart to download it again?
Hello, have you solved this problem? I’m also encountering the same issue and the map isn’t being generated. I re-downloaded the asset file, but the problem persisted.
