no map frame, no visual landmark when using isaac sim

[lalitsaraf]

I am new to isaac sim, visual slam tutorial with ros bag is working fine. I have tried a lot but couldn't do the visual slam with isaac sim on ware house scene. Its showing no map frame, and in the visual slam topics published its empty. and if i separately publish the tf between odom and map, its showing on rviz but still no visual landmark, and surprisingly. map topic is still not available in other terminals, its just available on rviz. I have see there were similar issues before which were resolved, but doing the same still couldn't figure out. Any help is highly appreciated. Thanks

I am following this tutorial https://nvidia-isaac-ros.github.io/concepts/visual_slam/cuvslam/tutorial_isaac_sim.html
