I'm running rolling on ubuntu 22.04 and have followed the tutorial here to create a custom IKFast plugin.

The plugin appears to be created properly and my kinematics.yaml file is appropriately updated:

Running /home/john/floyd2_ws/install/moveit_kinematics/lib/moveit_kinematics/create_ikfast_moveit_plugin.py "floyd" "floyd_arm" "floyd_floyd_arm_ikfast_plugin" "arm_base_link" "claw_palm" "/tmp/ikfast.KVsrLY/.openrave/kinematics.56100e0aa87ac8c4b7bff0d7b6dd20b9/ikfast0x10000049.Translation3D.0_1_2_f3_4.cpp"

However, after rebuilding my workspace (and sourcing install/setup.bash) I run into this error message when I launch the move_group.launch.py

[move_group-1] [ERROR] [1672685399.295029206] [kinematics_plugin_loader]: The kinematics plugin (floyd_floyd_arm/IKFastKinematicsPlugin) failed to load. Error: According to the loaded plugin descriptions the class floyd_floyd_arm/IKFastKinematicsPlugin with base class type kinematics::KinematicsBase does not exist. Declared types are  cached_ik_kinematics_plugin/CachedKDLKinematicsPlugin cached_ik_kinematics_plugin/CachedSrvKinematicsPlugin kdl_kinematics_plugin/KDLKinematicsPlugin lma_kinematics_plugin/LMAKinematicsPlugin prbt_manipulator/IKFastKinematicsPlugin srv_kinematics_plugin/SrvKinematicsPlugin

moveit setup assistant also doesn't recognize the plugin.

Is there another step I need to perform?
