平台业务流程开发踩坑

平台版本（v5.0.2）
1、回退上一节点异常--couldn't find a variable type that is able to serialize 11660；
2、回退上一节点异常--Error: unresolvable property or identifier: sum][Near : {... sum>2000 ....}]；
3、提交或回退时出现--[Error: failed to subEval expression][Near : {... sum<=1000 ....}]；

2、HKWF_TASK_FINISH_BEFORE，该函数需要定义上传该变量

function HKWF_TASK_FINISH_BEFORE() {
         // 获取申请单id
         //var id = FORM.getFormValue("id");
         var id = URL.getParameter("id");
         // 获取总金额
         var vsum = FORM.getFormValue("total_amount");
         vsum += "d";
         // 获取主表数据
     var vcomment = FORM.getFormValue("comment");
    
     var parame = {
                     comment : vcomment,
                     vars : {
                             id:id,
                             sum:vsum
                     }
     }
     console.log(parame);
     return parame;//将审批意见插入到流程数据库
   }

1、需要将上传的变量，变为字符串类型，

function HKWF_TASK_FINISH_BEFORE() {
         // 获取申请单id
         //var id = FORM.getFormValue("id");
         var id = URL.getParameter("id");
         // 获取总金额
         var vsum = FORM.getFormValue("total_amount");
         vsum += "d";
         // 获取主表数据
     var vcomment = FORM.getFormValue("comment");
    
     var parame = {
                     comment : vcomment,
                     vars : {
                             id:id,
                             sum:vsum
                     }
     }
     console.log(parame);
     return parame;//将审批意见插入到流程数据库
   }

3、变量的类型不一致导致的，异常具体如下：

解决方案：
=将类型转为一致的
如，Double.parseDouble(sum)>1000
=同时清理项目，重新部署
