<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 (so I'm posting it in both) . Either work fine independently but not together so there seems to be a conflict somewhere.

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

We encountered the same error this week. We use Wagtail 5.2 and django-simple-history in a project. After upgrading to django-simple-history 3.4.0 we encountered this error when attempting to preview a Wagtail page while editing the page. We do not encounter this error if we revert to django-simple-history 3.3.0.

I'm seeing the same issue here. Works fine with 3.3.* but fails as described with 3.4.0.

Previously the middleware made this check before deleting the request property from context, but with the refactor done in 3.4.0 it's gone

        if hasattr(HistoricalRecords.context, "request"):
            del HistoricalRecords.context.request

Hi, I'm the maintainer of Django Check SEO.

I tried to re-add the if hasattr ... condition in the middleware of django-simple-history, and I can confirm that it solves the problem encountered with django-check-seo.

Looks like @Tenzer and @ddabble fixed this in the master branch ~5 months ago. Can we get a new point release issued to fix this for those affected (includes me)?
