老师，我在电脑调试的时候没报错，可是到手机调试就报错了，能不能帮我分析一下,谢谢

错误如下：

thirdScriptError

errCode: -1  | errMsg: collection.doc:fail docId must not be empty; at collection.doc api; ; [Component] Event Handler Error @ pages/message_modification/message_modification#bound send

Error: errCode: -1  | errMsg: collection.doc:fail docId must not be empty; at collection.doc api;

错误显示的JS代码为:

db.collection('personal_information').doc(app.globalData.id).update({

// data 传入需要局部更新的数据

data: {

name: this.data.list.name

}
