Question

我想在新用户注册时在firestore中添加用户详细信息，但我在控制台中收到有关“未定义对象”的错误

功能：

  exports.storeUserData = functions.auth.user().onCreate(event =>{
    const user = event.data;
     var db_uid_user = db_firestore.collection('users').doc(user.uid).set({
        'name' : user.displayName,
        'email': user.email,
        'phoneNumber': user.phoneNumber,
        'photoUrl': user.photoURL

    });

     console.log('User Add (uid)',user.uid);

});

ERROR：

 Error: Cannot encode type ([object Undefined]) to a Firestore Value

所以，我忘了用户对象包含的细节受限于你使用什么样的Auth。

例如：如果您使用电子邮件和密码，您的用户对象将只有电子邮件，密码，uid。

因此

     'name' : user.displayName,        //invalid undefined object 
    'email': user.email,               //valid
    'phoneNumber': user.phoneNumber,   //invalid
    'photoUrl': user.photoURL          //invalid

错误：无法将类型（[对象未定义]）编码为Firestore值
