Как исправить "KeyError: '*'" в эластичном поиске

Question

Я пытаюсь реализовать эластичный поиск в своем проекте, но я получил эту ошибку, когда попытался запустить эту команду python manage.py index_orders

Я пытался изменить версиюasticsearch на последнюю (7.1.1) и запустите его.

Это мой командный класс, который я пытаюсь запустить

index_orders.py

class Command(BaseCommand):
    help = 'Indexes Orders in Elastic Search'

    def handle(self, *args, **options):
        es = Elasticsearch(
            [{'host': settings.ES_HOST, 'port': settings.ES_PORT}],
            index="order"
        )
        order_index = Index('order')
        order_index.doc_type(OrderDoc)
        if order_index.exists():
            order_index.delete()
            print('Deleted order index.')
        OrderDoc.init()
        result = bulk(
            client=es,
            actions=(order.indexing() for order in Order.objects.all().iterator())
        )
        print('Indexed orders.')
        print(result)
