Asp.net mvc Web-Api Checking checkbox all for Delete all data showing 500 error

I am trying to delete all records with checking all checkboxed values. but it is throwing 500 internal server error.

//delete all menu
function performalldeletemenu()
{

    if (confirm('Are you sure you want to delete this menu?'))
    {
        var AllCheckboxes = new Array();
        $("input:checked").each(function () {
            //console.log($(this).val()); //works fine
            AllCheckboxes .push($(this).val());
        });

        $.ajax({
            type: 'DELETE',
            url: '/api/MenuWebApi/DeleteAllMenu/',
            data: { deleteservice: AllCheckboxes },
            success: function (data) {
                if (data.Success == true) {
                    GetMenuList();
                }
            },
            error: function (xhr, textStatus, errorThrown) {
                //window.location = JsErrorAction;
            },
            dataType: "json",
            headers:
