GoogleNews- pygooglenews -Could not parse your date error

Using pygooglenews a month ago and it was working, however now there seems to be an error: Could not parse your date

Does anyone know how to bypass this or six this issue?

gn = GoogleNews(lang = 'en')

def get_news(search):
   stories = []
   start_date = datetime.date(2020,1,1)
   end_date = datetime.date(2021,12,31)
   delta = datetime.timedelta(days=1)
   date_list = pd.date_range(start_date, end_date).tolist()

for date in date_list[:-1]:
    result = gn.search(search, from_=(date).strftime('%Y-%m-%d'), to_=(date+delta).strftime('%Y-%m-%d'))
    newsitem = result['entries']

    for item in newsitem:
        story = {
            'title':item.title,

            'link':item.link,
            'published':item.published
        }
        stories.append(story)

return stories

I also tried just changing to simple date format

gn.search('Christmas', helper = True, from_ = '2019/12/01', to_= '2019/12/31')

and still getting Could not parse your date error.
