The issue names the Flink-Doris connector example and reports a DATE sink failure across the listed versions, but no source file or test is identified. Start by reproducing the example and tracing the DATE conversion from the connector input to the sink; done means the example no longer raises the Long-to-Integer ClassCastException and the expected DATE value is written.
