ValueError -Вид dashboard.views.saveBlogTopic не вернул объект HttpResponse. Вместо этого оно вернуло None

Я получил эту ошибку, когда попытался проверить свою функцию внутри views.py:

Traceback (последний последний вызов): Файл "/home//lib/python3.8/site-packages/django/core/handlers/exception.py", строка 55, in inner response = get_response(request) Файл "/home//lib/python3.8/site-packages/django/core/handlers/base.py", строка 204, in _get_response self.check_response(response, callback) Файл "/home/**/lib/python3.8/site-packages/django/core/handlers/base.py", строка 332, in check_response raise ValueError( ValueError: Представление dashboard.views.saveBlogTopic не вернуло объект HttpResponse. Вместо него возвращается None.

Я пробовал несколько способов решить проблему, но не смог. Можете ли вы мне помочь? вот мои файлы:
