Hi, the command ros2 launch that you launched was not complete. You need to include some extra information that you didn’t, that is why it failed.

This means that you still do not understand that command how it works. Go to the 3.2 Unit and start it again so you can see the structure of a typical ros2 command and what to expect. You need to study that unit in deep.
