No suitable driver found for jdbc:mysql

[brekko1st]

After 2 years I' trying to update our kafka-connect to latest version. Most of plugins works without any problems on new version except JdbcSinkConnector. I'm getting following error:

 No suitable driver found for jdbc:mysql://10.124.0.3:3306/kafka_testing\

I'm running it locally via docker compose. Here is the docker-compose file:

And here is dockerfile:

Here is the sink connector configuration:

}' http://localhost:8083/connectors/

I've checked documentation on:
https://docs.confluent.io/kafka-connectors/jdbc/current/jdbc-drivers.html
Checked this article:
https://www.confluent.io/blog/kafka-connect-deep-dive-jdbc-source-connector/
Stackoverflow and google searching.
I've tried different versions of mysq-connector.jar file. Try to push it into lib directory, component directory, java directory. Try different versions of kafka-connect-jdbc. Result is always the same. No suitable driver found. I've checked the logs and there is no info about registering the java driver.
