Why did the links stop working after adding the Sitemap?

Question

Django

Added a dynamic sitemap to the site. Everything works, sitemap.xml is created and all generated pages are displayed there. But after that, when entering any page of the site, there are errors.

sitemaps.py

class AudiobookSitemap(Sitemap):
    changefreq = "always"
    priority = 0.8
    protocol = 'http'

    def items(self):
        return AudioBook.objects.all()

    def lastmod(self, obj):
        return obj.created

    def location(self, obj):
        return '/audiobook/%s' % (obj.slug)


class BookGenreSitemap(Sitemap):
    changefreq = "always"
    priority = 0.9
    protocol = 'http'

    def items(self):
        return BookGenre.objects.all()

    def lastmod(self, obj):
        return obj.created

    def location(self, obj):
        return '/audiobook_genre/%s' % (obj.slug)

urls.py

app_name = "main"

sitemaps = {
    'audiobook':AudiobookSitemap,
    'audiobook_genre':BookGenreSitemap,
}

urlpatterns = [
    url(r'^$', views.home, name='home'),
    path('sitemap.xml', sitemap, {'sitemaps': sitemaps}, name='django.contrib.sitemaps.views.sitemap'),

    url('search/', SearchResultsView.as_view(), name='search'),

    path("author/<slug:post_slug>/", author, name='author'),
    path("cycle/<slug:post_slug>/", cycle, name='cycle'),

    path("audiobook/<slug:post_slug>/", audiobook, name='audiobook'),
    path("audiobook_genre/<slug:post_slug>/", audiobook_genre, name='audiobook_genre')

]

Well, the error itself when entering the site -

Reverse for 'search' not found. 'search' is not a valid view function or pattern name.
