Missing OdometryFlattenerNode in Isaac ROS 3.0

[vladmosoiu98]

Hi,

I am currently trying the setup done for the isaac-ros_dev repository, which uses the launch files from here.

I am encountering a problem, as the setup there suggests using the Isaac ROS 3.0 libraries for the demo.
What happens is that for isaac_ros_nvblox version 3.0 the Odometry Flattener node has been removed. I tried adding it manually from the 2.1 release but i get the following error when launching orbbec_dynamics_example.launch.py

[ERROR] [launch_ros.actions.load_composable_nodes]: Failed to load node 'odometry_flattener_node' of type 'nvblox::OdometryFlattenerNode' in container 'shared_nvblox_container': Could not find requested resource in ament index

The odometry_flatttener package did compile and was sourced before launch, but the error still persists.

Any ideas on how to bypass this?
