what's funny is that when I looked at the field being assigned, on

_Application.kt:101

, in the db, it's not defined as nullable...

Just before that I get this

[db-sql-netty-thread-2] WARN  c.g.j.sql.db.mysql.MySQLConnection - <mysql-connection-22> onResultSet - called without active query

and before that I get komappers'

TRACE org.komapper.SqlWithArgs

...

This error message says that a null was assigned to a non-null field. Can you show me your code? Maybe it Is a Driver issue? https://github.com/jasync-sql/jasync-sql/blob/2.2.4/mysql-async/src/main/java/com/github/jasync/sql/db/mysql/MySQLConnection.kt#L447
