01/18/2023, 10:11 PMHey Charlie - I'm looking into this now. Is it possible that you changed one of your assets from partitioned to non-partitioned in the middle of the backfill?

Charlie Bini
01/18/2023, 10:12 PMi wiped all materializations

Charlie Bini
01/19/2023, 12:24 AMHaven’t been able to access the backfills page actually

01/20/2023, 1:23 AM@sandy the culprit is a likely bad backfill record. now that I have enough backfills to paginate that view, it's working again. however, it will throw that error if I click to go to page 2
