NoReverseMatch в /force-password-change/ при смене пароля

Я использую систему пользователей django,

При попытке пользователя изменить пароль возникает ошибка, похожая на неправильную маршрутизацию url.

NoReverseMatch at /force-password-change/
Reverse for '' not found. '' is not a valid view function or pattern name.
Request Method: POST
Request URL:    http://localhost.example.jp:8010/force-password-change/

Эта ошибка происходит примерно здесь,

в users/views.py

class PasswordChangeView(LoginRequiredMixin, FormView):
    template_name = "users/password_change.html"
    form_class = PasswordChangeForm
    success_url = reverse_lazy("")

    def get(self, request, *args, **kwargs):
        form = self.form_class()
        user = get_object_or_404(User, username=self.request.user.username)
        return render(request, self.template_name,
                      {"form": form, "email": user.email})

    def post(self, request, *args, **kwargs):
        print("password is posted")
        form = self.form_class(request.POST)
        if form.is_valid():
            data = form.cleaned_data
            user = get_object_or_404(User, username=request.user.username)
            user.set_password(data["new_password1"])
            user.is_require_pwd_change = False
            user.save()
            return super(PasswordChangeView, self).form_valid(form)

        return super(PasswordChangeView, self).form_invalid(form)
