Repeat Server action no longer works in 3.7.5

Using NODE.js with a MS SQL Server db, I had a server action that found a recordset. then copied that recordset over to another table. The found recordset has multiple rows, so I setup a repeat to loop through the records. It worked great up until this morning when I upgraded to 3.7.5, opened up my project and of course it updated all the files. Now, my repeat fails. My error is cannot insert NULL value which looks to be like the insert step is no longer being populated by the query.
I have not made any changes at all, this is the result of the updated files.

Help @patrick! What changed??
