<asgiref.local.Local object at 0xffff8cab4f90> object has no attribute 'request'

I'm not sure if this is a django-check-seo issue or a django-simple-history issue. But if I enable the middleware of django-simple-history, it breaks django-check-seo. Either work fine independently but not together so there seems to be a conflict somewhere.

To reproduce the bug, install both apps, and the django-check-seo. Here's the traceback:
