Creating Software with Modern Diagramming Techniques: TypeError when trying to improve readability (page 20)

When I added Title: \n\n as instructed, trying to improve readability of the Title node, I got this error:

TypeError: Cannot read properties of undefined (reading 'members')

This happens both on and using the rendered included in the Obsidian editor (not sure how to find out which version it is)

after posting this, I realized I should have moved the line after the definition of the Title node. But the post was in the moderation queue and I could not interact with it until now.

Perhaps that should be mentioned in the text, as the lack of indications made it appear so that any place would be ok.

An excellent suggestion, thank you!
