Query/Question
The Push Notification System handle for the registration is invalid
Why is this not a Bug or a Feature Request?
I am sending the push notification to Android and apple devices from ASP.NET Core Web API. But most of the time in between push failed and I am getting the result as 'The Push Notification System handle for the registration is invalid'.
I do not understand this.
I am using the NotificationHub nuget package in my project. Package version in 4.0.0.
I am attaching the code below. Please help me with this issue.
`
public async static Task SendPushNotificationToDevice(HubNotification hub notification)
{
if (hubNotification != null)
{
try
{
NotificationHubClient hub =
NotificationHubClient.CreateClientFromConnectionString(ConfigurationManager.AppSettings["HubConnectionString"],
ConfigurationManager.AppSettings["HubName"], true);
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
if (!string.IsNullOrEmpty(hubNotification.DeviceId) && !string.IsNullOrEmpty(hubNotification.DeviceType))
{
//check if the already registered device
var registationDescriptions = hub.GetRegistrationsByTagAsync(hubNotification.ToUserEmail, 100).Result;
foreach (var registrationDescription in registationDescriptions)
{
// We shouldn't have any extra registrations; delete if we do.
hub.DeleteRegistrationAsync(registrationDescription);
}
