What happened
I previously used version 2.3.3 of SeaTunnel, and now I've upgraded to version 2.3.12, scheduling it through DolphinScheduler. However, I'm encountering failures with an error related to Hazelcast serialization. I haven't made any changes to my configuration except for updating the userparameter to usernamein the source section, and I'm using the new connector packages. The old version executes successfully, but the new version still fails.
