ROS2-Humble - Dynamixel Error: No module named ‘dynamixel_sdk_custom_interfaces’

[alikhorshidi]

Hello!
I’m using ROS2 Humble to control 2XL430-W250-T connected via U2D2
I followed this Video-Tutorial:

DYNAMIXEL Quick Start Guide for ROS 2

Everything goes right until this command:

ros2 topic pub /set_position dynamixel_sdk_custom_interfaces/msg/SetPosition
after SetPosition, normally by pressing Tab, It should looks like in the video:

ros2 topic pub /set_position dynamixel_sdk_custom_interfaces/msg/SetPosition "{id: 1, position: 1000}"

but unfortunately, it’s not working!! and typing by myself is not solve the problem.

I also tried publishing this topic (set_position) using rqt but when I want to add, it causes crash!
crash title is:

ModuleNotFoundError: No module named ‘dynamixel_sdk_custom_interfaces’

There is “dynamixel_sdk_custom_interfaces” folder:

Please help me.
