Question

我有一个对象数组；示例：listOfExpenses = [{...}, {...}, {...}]，当前它是一个空数组，我想向该数组添加一个对象。

我这样称呼：

const chatInstance = db.collection("chats").doc("1234567");

chatInstance.update({
  listOfExpenses: admin.firestore.FieldValue.arrayUnion({
    amount: 10,
    category: "food",
    date: "2019-06-16T07:25:26.010Z"
  })
});

这是我得到的错误

我不太确定自己在做什么错

当我遇到相同的错误时，这是因为我的firebase管理SDK admin实例与我用来获取firestore()实例的实例不同。您可能想尝试将示例代码段中的db替换为admin.firestore()，以确保您的情况并非如此

Firestore更新数组。调用无效数据的联合函数
