Verify whether we can improve Views' search transparency for other code errors

1. Edit existing View (or create a new one).
2. Add Relationship.
3. You should see the message: 'There are no relationships available to add.'

This is not something you see with every view you create in D8. You would have to have an entity with zero relationships for that to be shown. Core has none of those, so I think the steps need to be updated a bit (if this is reproducible at all).

Hi there, I wrote the patch I suppose, but I haven’t touched Drupal in over 5 years - never saw the GA of D8.

I believe the code diff is … trivial defensive programming. As I recall, “Custom Entities” were a powerful but poorly documented feature that became common building blocks in D8, and the foundational Views plugin became Core. So that may explain some of the disconnect.

If you’re looking for something that lacks relationships, I’d suppose you go through the flow of making a new entity type, then a View of that thing.

I believe the D7 flow of creating new Entities involved manually creating database tables, so there might be some edge-cases where this issue comes up.

Also, I can’t remember the difference between a “Node” and an “Entity” in Drupal anymore, so I maybe using terms incorrectly.
