Comment:

The `last` template filter is not intended to work with a queryset but
with a list, see
[https://docs.djangoproject.com/en/3.2/ref/templates/builtins/#last docs].
You can use `{{ queryset.last }}`, which will call
[https://docs.djangoproject.com/en/3.2/ref/models/querysets/#last
QuerySet.last()].
