I used ajax to create search and I get error every time in MVC

$("#btnSearch").click(function () {
                    var goverId = parseInt($("#SellerSearch_gover_id").val());
                    var cityId = parseInt($("#SellerSearch_city_id").val()) || 0;
                    var setData = $("#tableid");

                    setData.html("");
                    $.ajax({
                        type: "POST",
                        url: "/ReSeller/GetSearch?goverId" + goverId + "&cityId" + cityId,
                        contentType: "html",
                        success: function (result) {
                            if (result.length == 0) {
                                setData.append('<tr style="color: red; "><td colspan="3">No match data</td></tr>')
                            }
                            else {
                                $.each(result, function (index, value) {
                                    var Data = "<tr>" +
