Problem when doing a search with multiple results. NoReverseMatch

I am making a web application that uses the OpenLibrary API, using Django. In it I do a search within the API, if the results show more than one book, I get this error:

NoReverseMatch at /search-results/

Reverse for 'book_detail' with arguments '('reina-roja-red-queen', 'Reina Roja / Red Queen')' not found. 1 pattern(s) tried: ['books/((?P<slug>[-a-zA-Z0-9_]+)/(?P<title>[^/]+)+)']

My files are as follows:

urls.py

I want to be shown all the results and to be able to choose a book and to be taken to see in book_detail.html the data of the book.

path('books/<slug:slug>/<path:title>', views.book_detail, name='book_detail'),
