以下事务在Master角色上执行正常，在Follower角色上执行报错：errCode = 2, detailMessage = There are schema changes in one transaction, you can commit this transaction with formal data or rollback this whole transaction.请问是什么原因？
事务的完整语句如下：
begin;
Insert Into OPS.servreco (servreco_id, servreco_title, servreco_status, servreco_type, create_time, create_hospital_id, create_hospital_name, create_dept_id, create_dept_name, create_user_id, create_user_fullname, create_user_tel, ops_user_id, ops_user_fullname, ops_user_tel, handle_user_id, handle_user_fullname, handle_user_tel) Values ('7d13dc47-01ad-49a3-8b43-206cae7d91d4', 'csdnshds', '待审核', null, now(), 'ccb8bba4-0f07-4566-8585-a7eb473eb4b4', '测试医院', '123', '临床药学室', '7e67186e-1021-40e5-a4bd-3ea114201ad6', 'NCX', '18087298847', 'F829388FE1903683E0530204000AE18F', 'YH', '18408565186', 'F829388FE1903683E0530204000AE18F', 'YH', '18408565186');
