INC_04050736: Unexpected error while materializing query. Make sure all grouping and aggregations are not missing anything
and, while I'm about to update another - I think related - ticket w/ this information ( wait, after... I have an idea 😉 ), I would like to be able to dig in and try to troubleshoot some of these errors myself.
Is there a KB available with the error definitions and ideally examples of what may cause and resolve these errors?
