Hi @IRus,

This issue you're seeing was addressed in PR #1608 and that was fixed starting with version 3.14.4. Can you upgrade the JDBC driver and check if that addresses the issue, please?

Hey @IRus,

I'm just checking in to see if you were able to confirm that the newer JDBC driver releases starting with 3.14.4 address this problem.

@sfc-gh-wfateem Hi, I apologize for the delay, we were doing testing with new driver version.
Now it's deployed to production and the issue disappeared, thank you!
