AttributeError: 'NoneType' object has no attribute 'find'

爬取到一半后報錯，相關代碼如下

def?parse(self,?page_url,?html_cont):
????if?page_url?is?None?or?html_cont?is?None:
????????return
????soup?=?BeautifulSoup(html_cont,?'html.parser',?from_encoding='utf-8')
????new_urls?=?self._get_new_urls(page_url,?soup)
????new_data?=?self._get_new_data(page_url,?soup)
????return?new_urls,?new_data

求大神解答??！
