Error when building custom ros2 msg

edit

Hi, I am getting this error when attempting to build my custom ros2 msg. I followed this tutorial on creating a custom ros2 msg (https://docs.ros.org/en/crystal/Tutor...), but when i get to the final step of running:

colcon build --packages-select mbs_ros_msgs

I get the following error:

root@docker-desktop:/home/ros2_ws# colcon build --packages-select mbs_ros_msgs
Starting >>> mbs_ros_msgs
--- stderr: mbs_ros_msgs
