Не работает составной url

Django не находит путь, который я указал. Путь вида /title/number. Сколько не гуглил, решения не нашел. В ошибке по пути /title/number "Field 'number' expected a number but got 'dd'." В ошибке ниже в kwargs получены же нужные значения, почему тогда url принял dd, а не "1"?

callback
<function ChapterDetail at 0x000001ECD1EC9F78> callback_args
() callback_kwargs {'number': '1', 'slug': 'dd'} middleware_method
<bound method CsrfViewMiddleware.process_view of <django.middleware.csrf.CsrfViewMiddleware object at 0x000001ECD2074D88>> request <WSGIRequest: GET '/dd/1/'> response
None self
<django.core.handlers.wsgi.WSGIHandler object at 0x000001ECD17BE7C8> wrapped_callback
<function ChapterDetail at 0x000001ECD1EC9F78>

Как дать понять django, что я хочу путь /title/number ?
