Error when inserting data into MySQL

This is a known issue with MySQL Server below 8.0.26 with more recent connectors.

To use the recent connectors (8.0.23+) the server must also be upgraded to 8.0.26 or higher. As of June 22, 2021 this has not yet been released. As a workaround, you can uninstall the more recent connector and install 8.0.22 from mysql.org.
