NoReverseMatch в /polls/1/ в Django 4.0

Я изучаю Django по официальной документации и получаю такую ошибку:

NoReverseMatch at /polls/1/
Reverse for 'vote' with arguments '('',)' not found. 1 pattern(s) tried: ['polls/(?P<question_id>[0-9]+)/vote/\\Z']
Request Method: GET
Request URL:    http://127.0.0.1:8000/polls/1/
Django Version: 4.0
Exception Type: NoReverseMatch
Exception Value:    
Reverse for 'vote' with arguments '('',)' not found. 1 pattern(s) tried: ['polls/(?P<question_id>[0-9]+)/vote/\\Z']

Вот мои url-шаблоны:

urlpatterns = [
    path('', views.index, name='polls'),
    path('<int:question_id>/', views.detail, name='detail'),
    path('<int:question_id>/result/', views.result, name='result'),
    path('<int:question_id>/vote/', views.vote, name='vote'),
]

ФайлView.py:

def index(request):
    latest_questions = Question.objects.order_by('-pub_date')
    return render(request, 'polls/index.html', {'latest_questions': latest_questions})


def detail(request, question_id):
    detail = get_object_or_404(Question, pk=question_id)
    return render(request, 'polls/detail.html', {'detail': detail})


def result(request, question_id):
    return HttpResponse("This is the result for question no. %s" % question_id)


def vote(request, question_id):
    return HttpResponse("You are voting for question %s" % question_id)

Здесь проблема кроется в файле detail.html:

<form action="{% url 'vote' question.id %}" method="post">
