### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened Using the mysqlcdc source to get the mysql data and use the flink engine to synchronize it to starRocks and report an error. Looking at the error log, it seems to be a class implementation problem. ### SeaTunnel Version 2.3.1 ### SeaTunnel Config ```conf env { execution.parallelism = 1 job.mode = "STREAMING" checkpoint.interval = 2000 execution.planner = blink } source { MySQL-CDC { debezium { snapshot.mode = "never" decimal.handling.mode = "double" } startup.mode = "initial" result_table_name = "mysqlcdc" server-id = 5656 username = "BigData_canal" password = "TXojS3RaL8pwQqNs" table-names = ["finenter.writeoff_source"] base-url = "jdbc:mysql://192.168.240.123:8096/finenter" } } sink { StarRocks { nodeUrls = ["192.168.235.101:8030"] base-url = "jdbc:mysql://192.168.235.101:16033" username = ads_finenter_rd password = "d3673hl1" database = "ads_finenter" table = "writeoff_source_seatunnel" batch_max_rows = 10 starrocks.config = { format = "JSON" strip_outer_array = true } } } ``` ### Running Command ```shell ./bin/start-seatunnel-flink-15-connector-v2.sh --config config/example02.conf --deploy-mode run --target yarn-per-job ``` ### Error Exception ```log (72ca47b062541de96307f1515ce18081) switched from RUNNING to FAILED with failure cause: java.lang.UnsupportedOperationException: Flink ParallelSource don't support sending SourceEvent.
