When I add kolo.middleware.KoloMiddleware to the top of my middleware, django wont start up

[evanhitchen123]

DEBUG = True

MIDDLEWARE = [
    "kolo.middleware.KoloMiddleware",
    "django.middleware.security.SecurityMiddleware",
    "corsheaders.middleware.CorsMiddleware",
    "whitenoise.middleware.WhiteNoiseMiddleware",
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",
    "django.contrib.auth.middleware.AuthenticationMiddleware",
    "django.contrib.messages.middleware.MessageMiddleware",
    "django.middleware.clickjacking.XFrameOptionsMiddleware",
]

The following in my settings, then output on console:

Watching for file changes with StatReloader
Watching for file changes with StatReloader
Performing system checks...

System check identified no issues (0 silenced).

However, when I remove kolo middleware, it starts up fine

Interesting. Can you try moving it down through the list to see if it starts working in a different location? Perhaps there's a bad interaction with another middleware.

all my middleware and even at the bottom it freezes up

What are you running at the console? python manage.py runserver?

Does the context manager or decorator work?

@evanhitchen123 👋

Yeah super strange, haven't seen this before either!

Few more questions for you:

• which operating system and python version are you using?
• are you running Django in docker?
• when you make a request to Django with the kolo middleware present and it's frozen up, what happens? Does the request time out?

Ok so have solved this, not sure exactly why but for whatever reason, changing the name of my sqllite db resulted in it starting up eventually. I had been trying to get this to work with my docker arrangement but that will be my next step.

That is strange. I'd love to understand why that helped!
