Реверс для 'post_detail' с аргументами '('',)' не найден. Попытка 1 шаблона(ов): ['(?P<slug>[-a-zA-Z0-9_]+)/\\Z']

получаю следующую ошибку при добавлении ссылки возврата назад в моем comment_delete.html:

Повтор для 'post_detail' с аргументами '('',)' не найден. Испробован 1 шаблон(ы): ['(?P[-a-zA-Z0-9_]+)/\Z']

Все работает без ссылки на возврат (удаление комментария). Хотелось бы узнать, что я делаю не так в моем comment_delete (href="{% url 'post_detail' post.slug %}") Go back

Спасибо :)
