Send timestamp to firebase using firebase funtions-CodePudding

I need to save a date has a firebase Timestamp Object to Cloud Firestore using Firebase functions.

The code in question:

import FirebaseFunctions

lazy var functions = Functions.functions(region: "europe-west3")

let stamp = Timestamp(date: Date()) —> Not working

self.functions.httpsCallable("userUpdate").call(["id": user.uid, “startDate”: stamp]) { (result, error) in
                if let error = error {
                        print("##### update error \(error)”)
                    }
                }
                
                if let res = result {
                    if let fireData = (res.data as? [String: Any]) {
                        debugPrint("#####  Success update Data -> \(fireData["data"])")
                    }
                }
            }

The problem is that Firebase does not recognise the Timestamp format throwing a error:

'Unsupported type: FIRTimestamp for value <FIRTimestamp: seconds=1633262425 nanoseconds=843380928>'

If I try to send the date on the format below it works BUT the date on the server has the wrong format, it shows has a string and not has a Timestamp.

let date = DateFormatter.localizedString(from: Date(), dateStyle: .short, timeStyle: .none)

Any solutions for Firebase to recognise the date I'm sending has a Timestamp?

CodePudding user response：

Callable Cloud Functions only know how to send/receive JSON type, and Timestamp is not a JSON type.

The easiest way to work around this is to send the seconds and nanoseconds as separate numbers (which are valid JSON types) and then reconstruct a Timestamp object from those numberzs in the Cloud Functions code.
