New description:
This seems to be different from
https://code.djangoproject.com/ticket/32150 as it's about the ordering of
installed apps, not urls.
https://code.djangoproject.com/ticket/33955 could be related?
It also seems to be a regression: this works fine in 4.0 but not in 4.1 /
main.
This does not work, but if you reverse the order it works fine:
{{{
#!python
INSTALLED_APPS = [
...
"django.contrib.admindocs",
"django.contrib.admin",
]
}}}
With the error:
