Django.urls.exceptions.NoReverseMatch: Обратный поиск для 'activate' с аргументами в виде ключевых слов

Я не могу зарегистрировать нового пользователя из-за следующей ошибки:

django.urls.exceptions.NoReverseMatch: Reverse for 'activate' with keyword arguments '{'uid64': 'Mjk', 'token': 'aydhbh-1b0354ce0dd3df37193a6f22e95b0c4e'}' not found. 1 pattern(s) tried: ['account/activate/(?P<uidb64>[-a-zA-Z0-9_]+)/(?P<token>[-a-zA-Z0-9_]+)/$']

urls.py:

urlpatterns = [
    path('register/', views.account_register, name='register'),
    path('activate/<slug:uidb64>/<slug:token>/', views.account_activate, name='activate'),
    # User dashboard
    path('dashboard/', views.dashboard, name='dashboard'),
    ]

views.py:

def account_register(request):

        registerForm = RegistrationForm(request.POST)
        if registerForm.is_valid():

            user.email = registerForm.cleaned_data['email']

account_activation_email.html:
