Short description of error
Everything works, but the dashed line is red, I'm not sure how to explain it with words, so I created an example scene and a picture.
Example scene: bug_red_wire.blend
Exact steps for others to reproduce the error
Just open the example scene and you will see the red dashed wire.
In the modifier you can toggle the offset bool to see that everything is working as expected, so I suspect is a "mistake" in the evaluation chain that is not affecting functionality, just triggering the red color in the dashed wire.
UPDATE:
It seems that it happens because if you make an erroneous connection to a node, in this case the switch node, then you change the node type to the correct one, the erroneous connection is still being evaluated.
Check this video, complex to explain with words, easy to understand in video, very short, 2 minutes:

This was fixed a while ago.

or a similar commit.I appreciate you take the time to record a video like this, but it would be nice if you could try to keep it even shorter. There is no need to show all the ways that do work. Better just get straight to the point and show what's wrong. Thanks :)
