AJAX Проблемы с 304

Question

У меня есть вызов AJAX (попробуйте игнорировать всю сериализацию, эта часть работает на 100%), которая выдает 304. Как бы я это настроил, чтобы мои данные (flightResults) не перезаписывались пустым ответом 304тело?Код ниже ... извинения за длинный фрагмент, просто хочу, чтобы все это было там .. Спасибо!

        var app = {};
        app.init = function(){
          app.flightsGeo();
        };
        app.flightsGeo = function(){
          var location = resp.headers.get('Location');
          var sessionKey = location.substring(location.lastIndexOf("/") + 1);
          let updatedURL = `https://skyscanner-skyscanner-flight-search-v1.p.mashape.com/apiservices/pricing/uk2/v1.0/${sessionKey}?sortType=price&sortOrder=asc&pageIndex=0&pageSize=5`
          $.ajax({
