Ajax json doesnt show any instances

that even if i connected json data to ajax, it doesnt show me any results.

def get_json_categories(request):
    query_get = request.GET
    if query_get:
        query_get = query_get['q']
        categories = EcommerceProductCategory.objects.filter(name__contains=query_get).order_by('name')
    else:
        categories = EcommerceProductCategory.objects.order_by('name')

    data = {}
    data['results'] = []
    for category in categories:
        data_to_return = {}
        data_to_return['id'] = category.id
        data_to_return['name'] = category.name
        data['results'].append(data_to_return)

    return JsonResponse(data)

And i urled that to ecommerce/get_json_categories

and in the Django html

<div class="mt-2">
                <hr>
                <div class="form-group">
                    <select class="form-control w-30" name="category_select" id="category_select" aria-describedby="category_select" required></select>
                </div>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/select2.min.css" rel="stylesheet" />
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/select2.min.js"></script>
<script>
    $('#category_select').select2({
        placeholder: 'Wybierz kategorię',
        ajax: {
            url: 'http://127.0.0.1:8000/ecommerce/get_json_categories',
            dataType: 'json',
            data: function (params) {
                return {
                    q: params.term,
                    page: params.name
                };
            },
        }
    });
</script>

But it shows me “No results could be found” but that site (/ecommerce/get_json_categories) is full of json data.
