Firebase Cloud Function "too many HTTP redirects" - ios

Question

I'm trying to implement the https callable functions from firebase to my IOS app, but when I call the function from my device I get the following error:

Callable function:
import * as functions from "firebase-functions";
import * as admin from "firebase-admin";
admin.initializeApp();
// const fcm = admin.messaging();
const db = admin.firestore();
exports.addNumbers = functions.https.onCall((data) => {
// [END addFunctionTrigger]
// [START readAddData]
// Numbers passed from the client.
const firstNumber = data.firstNumber;
const secondNumber = data.secondNumber;
// [END readAddData]
// [START addHttpsError]
// Checking that attributes are present and are numbers.
if (!Number.isFinite(firstNumber) || !Number.isFinite(secondNumber)) {
// Throwing an HttpsError so that the client gets the error details.
throw new functions.https.HttpsError('invalid-argument', 'The function must be called with ' +
'two arguments "firstNumber" and "secondNumber" which must both be numbers.');
}
// [END addHttpsError]
// [START returnAddData]
// returning result.
return {
firstNumber: firstNumber,
secondNumber: secondNumber,
operator: '+',
operationResult: firstNumber + secondNumber,
};
// [END returnAddData]
});
Call from device(IOS, Swift):
func callNumbers() {
DispatchQueue.global(qos: .background).async {
functions.httpsCallable("addNumbers").call(["firstNumber": 10, "secondNumber": 5]) { result, error in
if let error = error as NSError? {
if error.domain == FunctionsErrorDomain {
let code = FunctionsErrorCode(rawValue: error.code)
let message = error.localizedDescription
let details = error.userInfo[FunctionsErrorDetailsKey]
}
// ...
}
if let data = result?.data {
print(data)
}
}
}
}
Does anyone know how I can fix this?
I'm trying to implement callable functions so that I can do important tasks from the server and not from the device.
