Запрос дублируется ⇐ Python

[Anonymous]

Первый запрос, который я делаю, должен заполнить базу данных, поэтому я написал что-то вроде этого:
# spider.py
def start_requests(self):
yield scrapy.Request(url=self.url, method='POST', callback=self.parse)

# middlewares.py DownloaderMiddleware process_request
.
.
.
except ValueError:
new_request = scrapy.Request(
url=request.url,
callback=request.callback,
method=request.method,
headers=request.headers,
body=self.body # was initialized in spider_opened method
)
return new_request

Проблема в том, что запрос никогда не доходит до метода синтаксического анализа, а дублируется. Запрос делается, параметры запроса правильные, но парсить его всё равно почему-то не получается.:
# spider.py
def parse(self, response):
logging.info('started parsing')
l = ItemLoader(FeedItem())
json_response = json.loads(response.text)

l.add_value('feed', json_response)

yield l.load_items()

yield scrapy.Request(url=self.url, method='POST', callback=self.parse)

Вот что я получаю:
