The target instance for import is MySQL

It looks like there was an issue parsing the MySQL version. Can you check the log?

Since Lightning is mainly used for importing into TiDB, it might not be as friendly with MySQL. If you can provide the log and the MySQL version to reproduce the issue, it might be resolved in the next version (you can use the select version() statement to read the MySQL version).
