MVC3 - Programmatic report image renders blank

[Justis]

I am trying to render a report as an image in my web service and return a byte[] to my client. The byte[] is then converted back into an image for display in the browser. From my debug sessions, I can see that byte[] does have data in it and the view appears to have a correctly sized image; however, the image is completely blank.

This report in particular requires one Integer parameter, ArgID, to be passed in. Blank values can not be accepted. Below is the code I am using (function names and arguments have been modified for brevity).

Web-Service code to render the report as an image:

public byte[] GetReport(int ArgID)
{
    try
    {
        Telerik.Reporting.Processing.ReportProcessor proc = new Telerik.Reporting.Processing.ReportProcessor();
        Telerik.Reporting.InstanceReportSource irs = new Telerik.Reporting.InstanceReportSource();

        Report1 report = new Report1();
        report.ReportParameters.Add(new Telerik.Reporting.ReportParameter("ArgID", Telerik.Reporting.ReportParameterType.Integer, ArgID));
        irs.ReportDocument = report;

        RenderingResult item = proc.RenderReport("IMAGE", irs, null);
        return item.DocumentBytes;
    }
    catch (Exception ex)
    {
        throw new FaultException(new FaultReason(ex.ToString()));
    }
}

View file img tag:

@model int
<img src="@Url.Action("GetReport", "Report", new { ID = Model })" alt="" />

Action called from img tag:

[HttpGet]
public ActionResult GetReport(int ID)
{
    byte[] img;
    using (var client = new MyService.MyServiceClient())
    {
        img = client.GetReport(ID);
    }
    return File(img, "image/tiff");
}

I've only just started using Telerik Reporting over SSRS and would like to make the case for switching to Telerik for a long-term solution if I can manage to get programmatic generation working within specifications. Any and all support is greatly appreciated.

Thank you,

Please disregard this thread. After further investigation, the issue is coming from an unhandled exception somewhere in our backend system.
