How can i send a large array to MVC Controller

Question

I am getting an error when sending an array with a length greater than 250 to MVC controller. It works when array length is less than 250 items.

Client Code

function saveVD() {
    var arr = [];
    $.each($("#tablevd tbody tr"), function () {
        arr.push({
                invNo: $(this).find('td:eq(0)').html().trim(),
                invDate: $(this).find('td:eq(1)').html().trim()
            })
    })
    $.ajax({
            contentType: 'application/json; charset=utf-8',
            dataType: 'json',
            type: 'POST',
            url: "@Url.Action("Absorb","My")",
            data: JSON.stringify({ 'arr': arr }),
            success: function (result) {
            },
            error: function () {
            }
        })
}

Server Code

public class MyController : Controller
{
    [HttpPost]
    public JsonResult Absorb(CIVM[] arr)
    {
        return Json(true, JsonRequestBehavior.AllowGet);
    }
}
public class CIVM
{
    public string invNo { get; set; }
    public DateTime invDate { get; set; }
}
