Hello @goldcold

Your problem is related to ROS Tutorials section.
We are in the process of refreshing and reproducing ROS Tutorials, which due to being based on ROS Melodic and some other issues may be out of date in some places and may throw errors in extreme cases. As soon as the part you’re having trouble with is updated, I’ll get back to you.
