gettext_lazy and url patterns

Using Django Mystery Errors
1

I have a quite complex application, which was working fine with Django 5.2.9 and does not work with django 6.0.

When I use the command runserver and I access any page I get:

A server error occurred. Please contact the administrator.

My main urls.py after removing everything else for testing purposes is:

from django.urls import include, path
from django.utils.translation import gettext_lazy


urlpatterns = [
    path(gettext_lazy('invitation/'), include('invitation.urls')),
]

and the invitation.urls is:

from django.urls import path
from django.utils.translation import gettext_lazy
from django.views.generic import TemplateView


urlpatterns = [
    path(gettext_lazy('request/'), TemplateView.as_view(template_name='invitation/request.html'), name='invitation.request'),
]

If I remove gettext_laxy from path(gettext_lazy('invitation/'), include('invitation.urls')) (but leaving it in invitation.urls) the error disappears.

If I remove it from invitation.urls but leave it in urls.py the error remains.

Something like the following in urls.py works just fine:

path(gettext_lazy('about/'), TemplateView.as_view(template_name='about.html'), name='about'),

The error I get in the console is the following:

TypeError: startswith first arg must be str or a tuple of str, not __proxy__

During handling of the above exception, another exception occurred:

(at this point the message above is repeated in an infinite loop).

It might be related to this commit:

amending it with:

elif path.startswith(str(self._route)):
    return path.removeprefix(str(self._route)), (), {}

fixes the issue.
