How to solve error with Reverse for 'app_list' with arguments?

Question

Django

added to admin.py :

def get_admin_urls(urls):
    def get_urls():
        my_urls = patterns('',
            (r'^service/expired_contracts/$', admin.site.admin_view(expired_contracts))
        )
        return my_urls + urls
    return get_urls

admin_urls = get_admin_urls(admin.site.get_urls())
admin.site.get_urls = admin_urls

i.e. in order to be able to call view.py in the admin panel, I needed to be able to view a certain report in the admin panel, which will be available at: /admin/service/expired_contracts
Everything works, but if you connect the change_list.html template, then I get the error
NoReverseMatch at /admin/service/expired_contracts/
Reverse for 'app_list' with arguments '()' and keyword arguments '{u'app_label': ''}' not found. 1 pattern(s) tried: [u'admin/(?Pauth|questionnaire)/$']
Help, what and where to fix? I'm still quite new to Django)
That is, I'm trying to integrate the view.py file into admin.py
