I feel like I read that if the CDT isn't set up correctly, it can lead to errors like this. So option A seems pretty likely to me.

I practiced a question similar to this, and I think syntax errors in rules can also lead to data retrieval issues. Maybe that's what's happening here?

Loren 7 months ago

I'm not entirely sure, but I think if the view has too many rows, it might just take longer to load. Could that be the problem?

Glendora 7 months ago

I remember something about primary keys being crucial for Views. If there's no column mapped as a primary key, that could definitely cause issues.
