When loading data I get an error “this list is too long to be processed”

Hi I update a database in my Bubble App every week from 2 centers. Today when I ran the larger center’s data upload I get this error “This list is too long to be processed” (see attached).
I’ve been running my App for months and don’t understand why at this time it is generating this error, btw the faulting data is the same size every week and the smaller center loads all it’s data fine(?) Does anyone have any ideas or suggestions?

Thanks Much!
