When I make an ajax call it prints the web page and does not enter the function

I try to make a simple ajax call but out of nowhere I started printing the ajax call and it no longer comes to the webmetod and everything is correct, it did not move anything and it started to fail in that way.

Ajax code

function getRecords(idExcel, tipoFile) {
    $("#IdRecords").removeClass("hidden");
    $.ajax({
        type: "GET",
        url: "AdminView.aspx/getInforRecords",
        data: '{idUpload:"' + idExcel + '",tipoFile:"' + tipoFile + '"}',
        contentType: 'application/json; charset=utf-8',
        dataType: "json",
        success: function (result) {
            return;
        },
        error: function (xhr, status, error) {
            alert(xhr.responseText)
        }
    });
}

.aspx.cs code

[WebMethod]
public string  getInforRecords(int idUpload,int tipoFile)
{
    UploadGEOController geocont = new UploadGEOController();
    List<UploadGEO> listgeo = new List<UploadGEO>();
    string htmlreturn = "";

    listgeo = geocont.RecordsExcel(idUpload,tipoFile);
    List<UploadGEO> lstreturn = new List<UploadGEO>();
    //foreach (UploadGEO elemento in listgeo)
    //{
    //    htmlreturn += "<tr><td>" + elemento.AreaFuncional + "</td><td>" + elemento.DominioFuncional + "</td><td>" + elemento.Periodo + "</td><td>" + elemento.Proveedor + "</td>" +
    //    "<td> <div class='col-lg-12 text-center'><i id='ModalRecords' class='fa fa-eye' title='Aqui Usted podra ver detalles'  aria-hidden='true' style='cursor:pointer;'></i></div>" +
    //    "" +
    //    "</td></tr>";

    //}

    lstreturn.AddRange(listgeo);

    return "";

}
