请求参数如下

{"touser":"xxxxxxxxxxxxx","data":{"time1":{"value":"15:01"},"amount3":{"value":"5"},"phrase2":{"value":"配送中"}},"template_id":"xxxxxxxxxxxxxxxxxxxxx","page":"/pages/index/index"}

返回数据如下

{"errcode":47003,"errmsg":"argument invalid! hint: [V_BwGa08713942] data.phrase2.value invalid"}

这是什么原因导致的，纳闷
