Реверс для 'detalle_reserva' с аргументами '('',)' не найден. Проверено 1 шаблон(ы): ['reserva/(?P<reserva_id>[^/]+)/\\\Z'].

Пожалуйста, помогите мне, я не знаю, почему я получаю эту ошибку, я следую учебнику youtube и не понимаю, почему ошибка.

я пробовал изменить путь в урлах, но это не помогло.

Я искал другие решения той же проблемы, и ни одно из них не работает.
