AttributeError: 'Provider' object has no attribute '_is_coroutine'

When I try to upgrade Django 3.2.16 to 4.1.4, I'm getting

AttributeError: 'Provider' object has no attribute '_is_coroutine'
  File "django/core/handlers/exception.py", line 55, in inner
    response = get_response(request)
  File "django/utils/deprecation.py", line 131, in __call__
    if self._is_coroutine:

I'm using the following in my list of MIDDLEWAREs:

MIDDLEWARE = [
    ...
    'raygun4py.middleware.django.Provider'
]

After checking the __init__ method in raygun4py's middleware, I realized that they do not call super().__init__(get_response), so they miss the self._async_check() call from MiddlewareMixin which causes this error.

A workaround for now can be this:

1. Create your own middleware that inherits Provider and calls self._async_check() by itself, such as this:

from raygun4py.middleware.django import Provider


class ProviderMiddleware(Provider):
  def __init__(self, get_response):
      super().__init__(get_response)
      self._async_check()

2. Replace 'raygun4py.middleware.django.Provider' in the MIDDLEWARE settings (located in your settings.py file) with your my_project.middleware.ProviderMiddleware implemented in step 1.
