iOS 客戶端調用函數，參數如下：func buyTicket(contestId: String, points: Int) -> SignalProducer<Void, Error> {    Functions.functions().httpsCallable("myFunction").call([        "userId": Auth.auth().currentUser!.uid,        "points": points,        "contestId": contestId            ], completion: ...然后在函數的開頭我有這個日志const userId = req.body.data.userId;const contestId = req.body.data.contestId;const points = req.body.data.points;console.log(`myFunction called with userId: ${userId} contestId: ${contestId} points: ${points}`);打印出來的是使用 userId 調用的 myFunction：BzoW5pWLbWRnd2UgjnTkfd3xfNf2 競賽Id：pBsQo0FHMyu4ay18dexy 點：[object Object]為什么點轉換為對象？當我嘗試將點傳遞給時，這導致我的函數崩潰FieldValue.increment
