activiti7整合seata异常

seata整合acitivti7服务启动成功，但是开启全局事物之后，在提交activiti的insert语句会报错，无效的列类型。如果去掉全局事物activiti又能正常运行，
seata服务器版本大概在1.3左右

Start with the Seata and Activiti 7 integration described in this issue, focusing on the global-transaction path where Activiti INSERT statements fail with an invalid column type. Check the attached screenshots and the reported Seata version around 1.3, then establish a reproducible setup and identify the database and exact failing statement. Done means the integration starts and the Activiti insert succeeds with global transactions enabled.
