LOAD DATA from file erroring after upgrade to 2025.1

We have a task that runs objectscript code to load data into a linked external table.  After upgrading from 2024.1 to 2025.1, the load is throwing an error, with error code -400, and no error message.  The data DOES get loaded into the external table in its entirety, so with no meaningful error message, its hard to determine what the issue is.  The result is the same with and without the USING clause, so don't let that confuse you.  We have logs of this statement succeeding before upgrade, and were able to get this statement to work in our production environment, which is still on version 2024.1.  I have recompiled all namespaces after upgrade, stopped and restarted the JDBC server, and have dropped and relinked the external table, all without success.

Code: LOAD DATA FROM FILE '/intersystems/filepath/loadtest.csv' INTO SCM_Table_sandbox.dontest USING {"maxerrors":0,"from": {"file": {"header":false,"columnseparator": ","}}}
