Ready API - JDBC request with Insert into Temp table using select not working

I have a JDBC request with a SQL query which is selecting few records and inserting them into temp table, this was working fine with the last Ready API version (3.3.0) that I was using. I recently updated to 3.30.0 and the same query is returning diffrent result like below. Anyone has any idea? Thanks
