$("#rider").autocomplete({

minLength: 3,

source: function (request, response) {

var term = request.term;

var classTypeId = viewModel.Entries()[viewModel.CurrentEntry()].ClassTypeId();

$.getJSON('<%= ResolveUrl("~/") %>DesktopModules/EventsAPI/Api/EventsService/FindRiders?ClassTypeId=' + classTypeId, request, function (data, status, xhr) {

response(data);

});

},

I got HTTP Error 404.0 - Not Found after I upgrade the dnn to 7.04.02
