Wagtailstreamforms TypeError from_db_value () отсутствует 1 обязательный позиционный аргумент: 'context'

Я получил эту ошибку при попытке использовать wagtailstreamforms. Построил среду с нуля и воспроизвел ошибку. Единственное, что я установил: 

Django==3.0.5
wagtail==2.8
wagtailstreamforms==3.9

В base.py добавлено (как предписано в документах): 

    'wagtail.contrib.modeladmin',
    'wagtailstreamforms'

Оставил все остальное нетронутым (стандартный Wagtail base.py), перенесла базу данных , Домашняя страница 127.0.0.1:8000 выдает страницу приветствия Wagtail, как и ожидалось, администратор находится на 127.0.0.1:8000/admin/ с элементом Streamforms в меню слева, как и ожидалось. Когда я нажимаю на нее, я могу создать форму, и когда я создаю первое поле для формы и затем сохраняю ее, я получаю ошибку выше. После этого я больше не могу получить доступ к разделу Streamforms, я сразу же получаю ту же ошибку при попытке.

Я просмотрел все сообщения на SO на wagtailstreamforms и многие подобные элементы на inte rnet, решения не найдено. Что я делаю не так?

Наконец-то нашел ответ. Wagtailstreamforms еще не поддерживает Django 3.0, хотя это не упоминается в документации. Существует одно изменение, которое, по-видимому, запланировано, но еще не отправлено, что вызывает ошибку, см. https://github.com/timonweb-forks/wagtailstreamforms/commit/57ff036593b43f4dd7926412d0075cefb934e5e5. После ручного изменения этого в моем env, все работает. Я дам знать разработчикам.
