Django exception middleware: TypeError: object() takes no parameters

jiango를 업그레이드하는 과정에서 settings를 수정합니다.py 이후 전체 오류 메시지는 다음과 같습니다.

TypeError: object() takes no parameters

오류 정보를 보려면middleware에 오류가 있습니다.Stackoverflow를 찾았는데 Django의 새 버전이 사용자 정의middleware의 쓰기 방식을 변경했습니다.https://docs.djangoproject.com/en/1.10/topics/http/middleware/#upgrading-pre-django-1-10-style-middleware 하지만settings.py에서 사용자 정의middleware를 사용하지 않았습니다. 다음과 같습니다.

MIDDLEWARE = [
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
]

settings에서.py에서 middleware를 찾으면 다음 코드가 표시됩니다.

if DEBUG:
    MIDDLEWARE = list(MIDDLEWARE)
    MIDDLEWARE.append('jiango.debug.middleware.SQLDebugMiddleware')

SQLDebugMiddleware를 변경하면 문제가 해결됩니다.
