Django request.session not working properly

i am creating a web app and i'm using ajax to send the data from frontend to backend so i can process the forms and save them to the database. I send the data from ajax to a get-data method and from there i save it to the session, and when i access the /success page and try to get the same data from session, it tells me that the key doesn't exist. How is that possible? Here is the code down below.

$.ajax({
      type: "POST",
      url: "/get-data/",
      data: JSON.stringify(obj),
      dataType: "text",
      headers: { "X-CSRFToken": getCookie("csrftoken") },
      success: function (response) {
        console.log("success"); // i get this, so i it means that the ajax works properly.
      },
      error: function (response, err, err2) {
        console.log(err2);
      },
    });

def get_data(request):
    if request.method == "POST":
        if is_ajax(request):
            rec_data = json.loads(request.body)
            print("the request came")
            request.session["data_check_form"] = rec_data
            print("everything set")
            print(request.session["data_check_form"])  # i print this and i get the json file properly
            return JsonResponse({"success": "200"})

def success_view(request):
    print("test")
    data = request.session.get("data_check_form", False) 
    print(data) # i get false
    ...

Use request.session.modified = True after any changes in session as

def get_data(request):
    if request.method == "POST":
        if is_ajax(request):
            rec_data = json.loads(request.body)
            print("the request came")
            request.session["data_check_form"] = rec_data
            request.session.modified = True
            print("everything set")
            print(request.session["data_check_form"])  # i print this and i get the json file properly
            return JsonResponse({"success": "200"})

Or you can set SESSION_SAVE_EVERY_REQUEST to True in settings.py which will save session to database on every single request as stated

To change this default behavior, set the SESSION_SAVE_EVERY_REQUEST setting to True. When set to True, Django will save the session to the database on every single request.
