Hello,

I have a workbench which includes Databrick JDBC Connection. It was working fine with FME 2024.0.3.0. However, after upgrading to FME 2024.1.2.1, it starts throwing error “java.sql.SQLException: iDatabricks]iDatabricksJDBCDriver](500151) Error setting/closing session: Connection not obtained from this manager.”

Feels like something is missing with the upgrade. Has anybody seen the same problem? Could Safe support team please check? thank you.

Full error attached below.
