Copy to SQL Server fails, possibly related to security filters?

I’m trying to copy an app built on top of google sheets into an Azure SQL Server. I am also using security filters on every table in my app:

The copy fails (very quickly, in less than 2-3 seconds) with this error:


One of the tables, evidently the first one we tried to copy, is called “endusers”. And it was in fact created, e.g.:

(there are correctly 4 records in this table)

Anyone know if security filters and the copy command are mutually exclusive?

I was able to confirm that this is not related to appsheet security filters generally, but rather something about azure sql server itself. I was able to perform the above to postgres on aws. Still tracking this down…
