I have repeated this problem, and I think it is the dependency conflict. I am currently investigating which part of the dependency has the problem, and I will inform you if there is more progress

Your effort is greatly appreciated. This problem has significantly stalled our progress on dolphinscheduler, which is a must-use tool for us. We're eagerly awaiting any further insights you might have.

I resolved the problem by upgrading the clickhouse-jdbc package to version 0.4.6 and disabling SerializationFeature.FAIL_ON_EMPTY_BEANS in the objectMapper within the JSONUtils class of the dolphinscheduler-common package.At present, running SQL queries on either ClickHouse or Byconity via DolphinScheduler is functioning normally.

I am uncertain whether these changes could potentially lead to other underlying problems.

I am not sure if it will cause issues such as memory leaks.
