FlexConnector Database : Unknown initial character set index '255' received from server

Hi All,

Trying to create ID Based Database Flex Connector

Environment:

- SmartConnector 8.30

- Database target : MySQL 8.0.25-15

After configuring the flex , the following error appeared in the log file

java.sql.SQLException: Unknown initial character set index '255' received from server. Initial client character set can be forced via the 'characterEncoding' property.

Tried modifying the JDBC connection string to : jdbc://<SERVERIP>:3306/<DBNAME>?characterEncoding=utf8 , but the problem persisted.

Any ideas ?

Thanks
