I can trigger a failure to load swagger when SECRET_KEY in django's settings.py file is changed. There is no such failure with redoc, though there are some load failures.

Very dumb mistake.

[wdongdongde]

so, how to solve this problem?

I needed to add 'whitenoise.middleware.WhiteNoiseMiddleware' in the MIDDLEWARE = [] list in my settings.py
