Does not store cookies. What could be?

Question

Django

Good day.
I am developing a store on Django-Oscar. After numerous edits, the block "recently viewed products" disappeared. The products on the page are available through templatetag:

@register.inclusion_tag('customer/history/recently_viewed_products.html',
                        takes_context=True)
def recently_viewed_products(context):
    """
    Inclusion tag listing the most recently viewed products
    """
    # import pdb; pdb.set_trace() # debug yskhlyan
    request = context['request']
    products = history.get(request)
    return {'products': products,
            'request': request}

history.get(request)looks like this:

def get(request):
    """
    Return a list of recently viewed products
    """
    ids = extract(request)

    # Reordering as the ID order gets messed up in the query
    product_dict = Product.browsable.in_bulk(ids)
    ids.reverse()
    return [product_dict[id] for id in ids if id in product_dict]


def extract(request, response=None):
    """
    Extract the IDs of products in the history cookie
    """
    ids = []
    cookie_name = settings.OSCAR_RECENTLY_VIEWED_COOKIE_NAME
    if cookie_name in request.COOKIES:
        try:
            ids = json.loads(request.COOKIES[cookie_name])
        except ValueError:
            # This can occur if something messes up the cookie
            if response:
                response.delete_cookie(cookie_name)
        else:
            # Badly written web crawlers send garbage in double quotes
            if not isinstance(ids, list):
                ids = []
    return ids

Then pdbI looked at request.COOKIES, and there is no necessary key in it (

settings.OSCAR_RECENTLY_VIEWED_COOKIE_NAME = 'oscar_history'

)
What could be the problem? If you need to show other methods - write, I will add to the question.
I will be very grateful for your help.

Solved a problem.
Registered in __init__.py:

default_app_config = 'apps.customer.config.CustomerConfig'
