Akka Persistence: No Sufficient Working Example for JDBC MySQL - akka

Question

I have been trying to get my EventSourceBehavior to write to MySQL and am getting following error, what could be the issue? Error is very generic and it is hard to see what is the root cause. Is there a way to test wether my JDBC is correctly configured via Akka, ex connectivity etc, Thanks

In general, with Akka Persistence JDBC, you'll need to specify the database to use, not just the DBMS (server) to connect to. So if the DB was called my_akka_persistence, the JDBC URL would be something like jdbc:mysql://localhost:3306/my_akka_persistence.
