iOS: Push notification causes multiple calls to OnReceived and app crashing

[Yahya0007]

Hi

First time sending push notifications via code. I have this problem on iOS only. Android works fine.

Sending push notifications to IOS device from Firebase Console works fine.

When I send push notification using below code the OnReceived is called multiple times (approx. six, seven) and then the iOS app crashes.

Any help to resolves this would be appreciated.

Thanks

Regards

    private async Task<bool> SendFirebaseNotification(SqlConnection connection, List<string> pushTokens, string title, string body, string user, Guid guid)
    {
        var basePath = AppDomain.CurrentDomain.BaseDirectory;
        var credentialPath = Path.Combine(basePath, "private_key.json");

        if (FirebaseApp.DefaultInstance == null)
        {
            FirebaseApp.Create(new AppOptions()
            {
                Credential = GoogleCredential.FromFile(credentialPath)
            });
        }

        Guid g = guid;

        var message = new FirebaseAdmin.Messaging.MulticastMessage()
        {
            Tokens = pushTokens,
            Apns = new ApnsConfig()
            {
                Headers = new Dictionary<string, string>
                {
                    { "apns-priority", "10" }, // High priority
                    { "apns-push-type", "alert" } // Alert push type for iOS 13+
                },
                Aps = new Aps()
                {
                    ContentAvailable = true,
                    Alert = new ApsAlert()
                    {
                        Title = title,
                        Body = body
                    },
                    Sound = "default" // Default sound
                }
            },
            Notification = new FirebaseAdmin.Messaging.Notification
            {
                Title = title,
                Body = body,
            },
            Data = new Dictionary<string, string>
            {
                { "click_action", "SHINY_PUSH_NOTIFICATION_CLICK" },
                { "data", "my_silent_data" },
                { "StaffID", "-1" },
                { "EventID", "-1" },
                { "StaffBooking", "-1" },
                { "Comments", "" },
                { "Action", "" },
                { "ActionPayload", "" },
                { "User", user },
                { "GUID", g.ToString() },
                { "Title", title },
                { "Message", body },
            },
            Android = new AndroidConfig
            {
                Notification = new AndroidNotification
                {
                    ClickAction = "SHINY_PUSH_NOTIFICATION_CLICK",
                    Title = title,
                    Body = body,
                    Sound = "default", // Default sound for Android
                },
            },
        };

        var response = await FirebaseMessaging.DefaultInstance.SendEachForMulticastAsync(message);
    }
