That’s a very generic message. It means it tried to read an item from a collection, but the item wasn’t there. That collection could be any number of things, like menu items, business records, etc.

Whoever diagnoses this will likely need more information. What was the user doing when they saw this? Is it repeatable?

This is a sporadic issue when trying to open Schedule board ,so it will be difficult to diagnose. Thank you!
