英文:
Copy a firestore document to another collection from firebase trigger function
问题
I want to sync my doc to another collection based on the firebase trigger function.
我想根据 firebase 触发函数 将我的文档同步到另一个集合。
exports.foo = functions
.region("foo")
.firestore.document("foo")
.onWrite((events, context) => {
return new Promise((resolve, reject) => {
if (events.after.exists) {
// on create or update
admin
.firestore().doc("newFoo")
.set(events.after.data)
.then(() => { resolve(true); })
.catch((ex) => { reject(ex); });
} else{
// on delete
admin
.firestore()
.doc("newFoo")
.delete()
.then(() => { resolve(true); })
.catch((ex) => { reject(ex); });
}
});
});
但是当我尝试在 Firestore 中手动编辑我的文档时，我收到以下错误：
> Error: Value for argument "data" is not a valid Firestore document.
> Input is not a plain JavaScript object.
为什么会出现这个错误？根据我的检查，events.after.data 也返回了一个 FirebaseFirestore.DocumentData，这是 doc.set() 的正确数据类型。

.catch((ex) => { reject(ex); });
} else{
// on delete
admin
.firestore()
.doc("newFoo")
.delete()
.then(() => { resolve(true); })
.catch((ex) => { reject(ex); });
}
});
});
but I got the following error when I try to manually edit my document in firestore
> Error: Value for argument "data" is not a valid Firestore document.
> Input is not a plain JavaScript object.
why do I get the error? as I check, the events.after.data is also returning a FirebaseFirestore.DocumentData which is the correct data type for doc.set()

得分: 1
.set(events.after.data) 应该改为 .set(events.after.data())，因为 data 是一个方法而不是属性。
英文:
This line .set(events.after.data) should be .set(events.after.data()) as data is a method not a property.
