/nvblox_node/static_map_slice Unavailable

[gOrca]

Situation
NVIDIA Jetson AGX Orin Developer Kit - Jetpack 6.0 [L4T 36.3.0];
Currently running the following:
Isaac ROS Container + NVBlox + NVBlox / Nav2 plugin + Nav2.

Expected Outcome #1

• Launch RVIz
• Add → “By display type” → nvblox_rviz_plugin
• I should see “static_map_slice” topic for RViz visualization purposes.

Expected Outcome #2

• In separate terminal, enter “ros2 topic echo /nvblox_node/static_map_slice”
• Output that does not look like list of "1000", which, from what I can gather, signifies "no data"

Actual Outcome #1

• Launch RVIz
• Add → “By display type” → nvblox_rviz_plugin
• No “static_map_slice” topic to visualize
  Actual Outcome Isaac ROS 0.9.3 (EA3) #2
  Back in terminal, ros2 topic echo /nvblox_node/static_map_slice shows a constant “1000.0”, which, based on digging around forum, seems to be the default value for “unknown”, or “no static_map_slice” data, or “not functional?”

Question:
What is the expected output of ‘static_map_slice’, in “standalone mode” (i.e., Isaac ROS + NVBlox + NVBlox Plugin)?

Note:
I am able to successfully visualize the following:

/nvblox_node/mesh,
/nvblox_node/color_layer,
/nvblox_node/static_esdf_pointcloud (which actually outputs a costmap slice that I expect to see)
