Calendar API NextSyncToken always empty

I am using a combination of NextSyncToken and NextPageToken.

PageToken seems to work perfectly, but NextSyncToken is empty all the time? See code below:

     Events events;
        String pageToken = null;
        do
        {
            request.PageToken = pageToken;
            events = request.Execute();


            Console.WriteLine(events.Items.Count);
            if (events.Items != null && events.Items.Count > 0)
            {
                foreach (var eventItem in events.Items)
                {
                    string when = eventItem.Start.DateTime.ToString();
                    if (String.IsNullOrEmpty(when))
                    {
                        when = eventItem.Start.Date;
                    }

                }
            }
            else
            {
                Console.WriteLine("No upcoming events found.");
            }
            pageToken = events.NextPageToken;

        } while (events.NextPageToken != null);



        Console.WriteLine("synch token " + events.NextSyncToken);
        Console.WriteLine("page token " + events.NextPageToken);

The expected behavior is that the synctoken is on the last page however it is null.

Hi

I have managed to find out why. It seems synch token is broken when using the following option:

        EventsResource.ListRequest request = service.Events.List("primary");
        request.TimeMin = DateTime.Now;
        request.ShowDeleted = true;
        request.SingleEvents = true;
        request.MaxResults = 100;

–> BREAKS --> request.OrderBy = EventsResource.ListRequest.OrderByEnum.StartTime;

Why is this closed ? Using the orderBy param also breaks js client, but I can’t find any documentation about this. If the nextSyncToken is not provided on purpose, this behaviour should at least be clearly documented in the relevant docs.
