Question

我有这个代码

this.db.collection("users").doc(this.name_user).update({
        data
        })
        .then(function() {})
        .catch(function(error) {
          console.log("Error! " + error);
        });

执行代码后，出现以下错误

core.js:1449 ERROR Error: Function DocumentReference.update() called with invalid data. Unsupported field value: undefined
at new FirestoreError (error.js:149)
at ParseContext.createError (user_data_converter.js:162)
at UserDataConverter.parseScalarValue (user_data_converter.js:439)

at UserDataConverter.parseArray (user_data_converter.js:347)
at UserDataConverter.parseData (user_data_converter.js:327)

知道为什么会发生此错误吗？或者我的代码有问题吗？

我收到一个json并使用FOR循环处理数据，这是代码：

for (var i = 0; i < data.length; i++) {
    if(data[i].id_expediente === this.id_exp ){
      console.log("update status");

     datos.splice(i, 1, {id_exp: data[i].id_exp,
        demandado: data[i].name,
        direccion: data[i].address,
        status: "start"
      });
    }
}

（在此之后）用于打印控制台数据

[

{
  "id_exp": "8989",
  "name": "user_name",
  "address: "Mexico, Mexico",
  "status": "start"
}
,
{
"id_exp": "8990",
  "name": "user_name2",
  "address": "Mexico, Mexico",
  "status": ""
},
{
"id_exp": "8995",
  "name": "user_name3",
  "address": "Mexico, Mexico",
  "status": ""
}
]

firestore，错误错误：函数DocumentReference.update（）用无效数据调用。不支持的字段值：未定义
