JDBC Connector issue in the Kaalon 7

java.sql.SQLException: Unknown system variable ‘performance_schema’ --This issue remains even after manually uploaded the my-connector 6.0.6.This problem araised after upgrading into katalon version 7!! Can we downgrade the JDBC driver

It would be interesting to see more information then just this, for example code, error log, etc. Anything that could be related to the issue

is there any solution for this issue ?? Please look into this.
