根据实际期望实现需求，应使用节点变量，使用模型变量导致异常报错，此处实例为发卡人员来自上个人工表单提交的数据，使用节点变量符合较符合实现场景。
其中节点变量含义为每个节点输出的变量。人工/签核节点输出的节点变量为同意/提交的数据 。。自动节点的节点变量为撰写返回脚本return的json内容
模型的概念：基于实际业务场景设计的数据库表结构。
模型变量的概念：开发平台下基于业务场景设计的表结构json数据。例如以下json就是一个含有三条零件数据的零件模型变量{

适用于用节点变量的场景：需求明确到一个特定节点提交数据，例如设定一个关卡的发卡人特德的人上个关卡中的一个业务字段，那么此时可以指定发卡人取节点变量特定字段
使用于使用模型变量：实现场景针对是当前流程中的某一特定业务字段，非哪个节点的特定提交输出，例如多人签核中的签核状态非拒绝此时需求不特定某个特定节点，只要是签核状态为拒绝则执行某种动作，此场景适用模型变量 |
