Tutorial fails when instructions followed and CycloneDDS used on Iron

[dsandber]

I followed the instructions for the MoveIt2 source build here:

https://moveit.ros.org/install-moveit2/source/

This involved using Cyclone DDS.

When I ran the following:

ros2 launch moveit2_tutorials motion_planning_python_api_tutorial.launch.py

I got a lot of errors (attached) and the arm didn't move. When I removed the export RMW_IMPLEMENTATION=rmw_cyclonedds_cpp line and used the default middle-ware for Ubuntu Iron binary installation, everything worked fine. Perhaps this issue comes from mixing the Ubuntu 22.04 Iron ROS2 binary installation with a MoveIt2 source installation?

I'd suggest changing the instructions above to not recommend using the Cyclone DDS on an iron build. The main ROS2 instructions I believe also don't recommend it for Iron. This might be the cause of #866 and #804 as well.
