Python + Scrapy + JSON: у объекта 'NoneType' нет атрибута 'body_as_unicode'

Question

Я пытаюсь очистить все URL с этой JSON-страницы с помощью Scrapy в Python:

view-source: https://highape.com/bangalore/all-events

Но всякий раз, когда я пишу этот код на моей оболочке Scrapy:

import json #it works

jsonresponse = json.loads(response.body_as_unicode())

Я получаю следующую ошибку:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
AttributeError: 'NoneType' object has no attribute 'body_as_unicode'

Это часть этого большого файла JSON:

Мне нужно очистить URL-адреса, как это(было бы весьма полезно, если бы вы предложили решение без привлечения Beautiful Soup):

 "url":"https://highape.com/bangalore/events/combo-offers-at-fill-n-chill-QRkdny0WXv"
