Kendo UI Scheduler incorrectly calling WebAPI - asp.net-core

Question

I have been looking around the Telerik forums & Stackoverflow for an answer for this and I am completely stuck and unable to figure out the issue.
I am using the Kendo UI for Asp.Net Core Scheduler Control. I have it reading the data from my controller fine. However, I cannot get it call the HttpPut handler correctly.
When checking the traffic I get the following response, and therefor my breakpoint inside my HttpPut handler will never be hit.
400 - Bad Request
{"":["The input was not valid."]}
My code in my view is:
#(Html.Kendo().Scheduler<MeetingViewModel>()
.Name("SchedulerView")
.Height(500)
.Date(DateTime.Now.ToUniversalTime())
.StartTime(new DateTime(2018, 11, 28, 0, 00, 00).ToUniversalTime())
.MajorTick(30)
.ShowWorkHours(false)
.Footer(false)
.Editable(edit =>
{
//edit.Resize(false);
edit.Create(false);
})
.Views(views =>
{
views.TimelineView(timeline => timeline.EventHeight(50));
//views.TimelineWeekView(timeline => timeline.EventHeight(50));
//views.TimelineWorkWeekView(timeline => timeline.EventHeight(50));
//views.TimelineMonthView(timeline =>
//{
// timeline.StartTime(DateTime.Now);
// timeline.EndTime(DateTime.Now.AddMonths(1));
// timeline.MajorTick(1440);
// timeline.EventHeight(50);
//});
})
.Timezone("Etc/UTC")
.Group(group => group.Resources("WorkCenters" /*,"Attendees"*/).Orientation(SchedulerGroupOrientation.Vertical))
.Resources(resource =>
{
resource.Add(m => m.ScheduleRowID)
.Title("Work Center")
.Name("WorkCenters")
.DataTextField("Text")
.DataValueField("Value")
.DataColorField("Color")
.BindTo(#Model.AvailableWorkCenters);
})
.DataSource(d => d
.ServerOperation(true)
.WebApi()
.Model(m =>
{
m.Id(f => f.ActivityID);
m.Field(f => f.Title).DefaultValue("No title");
//m.RecurrenceId(f => f.RecurrenceID);
m.Field(f => f.Description).DefaultValue("No Description");
})
.Events(events => events.Error("error_handler"))
.Read(read => read.Action("GetActivities", "Scheduler").Data("setRequestDateTimes"))
//.Create(create => create.Action("Post", "Scheduler"))
.Update(update => update.Action("PutActivity", "Scheduler", new { id = "{0}" }).Type(HttpVerbs.Put))
//.Destroy(destroy => destroy.Action("Delete", "Scheduler", new { id = "{0}" }))
)))
And my API Controller is as follows:
[Route("Api/[controller]")]
[ApiController]
public class SchedulerController : DawnController
{
public SchedulerController(DatabaseContext context) : base(context)
{
}
[HttpGet]
public DataSourceResult GetActivities([DataSourceRequest] DataSourceRequest request, DateTime requestStartDateTime, DateTime requestEndDateTime)
{
//Kendo doesnt seem to send the full date range. so + 1 day to end
requestEndDateTime = requestEndDateTime.AddDays(1);
List<MeetingViewModel> test = new List<MeetingViewModel>();
foreach (JobTask jobTask in Context.JobTask)
{
if (JobTask.HasActivityInDateRange(jobTask, requestStartDateTime, requestEndDateTime))
{
foreach (Activites jobTaskAct in jobTask.Activites)
{
test.Add(new MeetingViewModel()
{
JobTaskID = jobTask.JobTaskId,
ActivityID = jobTaskAct.ActivityId,
Title = jobTaskAct.Name,
Description = jobTaskAct.Description,
Start = jobTaskAct.StartTime.ToUniversalTime(),
End = jobTaskAct.EndTime.ToUniversalTime(),
IsAllDay = false,
ScheduleRowID = jobTaskAct.Workcenter.WorkCenterId,
});
}
}
}
return test.ToDataSourceResult(request);
}
[HttpPut("{id}")]
public IActionResult PutActivity(int id, MeetingViewModel task)
{
if (ModelState.IsValid && id == task.ActivityID)
{
try
{
//breakpoint here
bool a = true;
//update the db here
}
catch (DbUpdateConcurrencyException)
{
return new NotFoundResult();
}
return new StatusCodeResult(200);
}
else
{
return BadRequest(ModelState.Values.SelectMany(v => v.Errors).Select(error => error.ErrorMessage));
}
}
}
Thanks

The URL exposing your controller method PutActivity in your controller example is PUT api/scheduler/{id}
To access that URL use this Update method.
.Update(update => update.Action("Put", "Scheduler", new { id = "{0}" }))
See this demo as example
Alternatively
If you want to implment the URL api/Scheduler/PutActivity/{id} (similar pattern to your GET) then you will need to modify the attribute over the put method as follows.
[HttpPut("PutActivity/{id}")]
public IActionResult PutActivity(int id, MeetingViewModel task)
Then you can call api/Scheduler/PutActivity/{id} with this asp.net action call.
.Update(update => update.Action("PutActivity", "Scheduler", new { id = "{0}" }).Type(HttpVerbs.Put))
