Unit 6 - Component not created

In Unit 6 - Node composition.

I am currently following the Node composition tutorial, i build without any error, using the colcon build, then source the install/setup.bash but i cant see my component using the :

ros2 component types

the component does not appear int the list. I followed and verified each steps but can’t figure what is missing or wrong.

Hello @davidlinhares ,

I’ve been doing some tests and it’s working ok for me. Could you please try the following command:

ros2 component types | grep my_components

You don’t get any output from this command?
