Cannot start ROS2 node

When I ran ros2 topic list on my M2 Macbook Air running MATLAB 2024b I get the following error:

Error using ros2 (line 117)

Error creating the ROS 2 node /_matlab_introspec__0_rmw_fastrtps_cpp.

Caused by:

Unrecognized field name "CustomMessageMapVersion".

I had just launched MATLAB and not run any other commands beforehand; the workspace is clear.

I have ROS2 Humble and Jazzy installed in different virtual machines. I would like to connect to a ROS2 Jazzy virtual machine running in UTM so that I can do simulations with the new Gazebo. I hope this is possible! Thanks!

Hi Antonia,

Can you share the output of the following commands in MATLAB to help on this issue:

pref = getpref('ROS_Toolbox')

and

share rossupport.txt file generated by executing

ros.internal.generateSupportFile

Thanks,

Karthik Reddy

Hello Antonia,

I was also facing the same error while using ROS2 in one of my workflows.

Upon some research, I found that following the given steps in this GitHub issue comment resolved it for me: https://github.com/eProsima/Fast-DDS/issues/2003#issuecomment-1160245640

I recommend you to try the same.
