When employing breadcrumbs,
generated as (example) 
home > articles > subdir

if the user is in node subdir viewing files, then clicks articles to go up one level,
I am getting from cocoon
The requested resource "/articles/" could not be found
this link's absolute path during testing is http://localhost:8888/articles/
I threw in an index.html file
when you manually enter the index.html in the browser path after articles/ you get the page but
even if sitemap has match="articles/index.html" cocoon still isn't happy with request articles/

core log tells me this in a nutshell:
