   ### What happened
   
   seatunnel2.3.9 的mysqlCDC 
Source在配置了table-pattern选项时，任务运行中如果创建了新表且表名满足table-pattern中的正则表达式，那么在新表有数据变化时，seatunnel任务会报错
   
   ### SeaTunnel Version
   
   2.3.9
   
   ### SeaTunnel Config
   
   ```conf
   env {
     job.name = "mysqlCDC_console_test"
     job.mode = "STREAMING"  
     checkpoint.interval = 10000
     checkpoint.timeout = 600000
     parallelism = 1
   }

         format = "json",
         read_json_by_line = "true"
       }
     }
   
     Doris {

       table = "${target_tab_name2}"
       strict_mode = "false"
       sink.label-prefix = "test-cdc"
