As a "service worker newbie" I encountered a related situation whereby a service worker wouldn't refresh even though the "JavaScript Console>Application>Update on reload" was enabled on Chrome Canary.

When I introduced the error the browser refused to load the updated code and continued to load the earlier working service worker. When I corrected the code in index.js and refreshed the page the new code for the service worker appeared. I would have thought that the error filled code would throw an error, but it didn't. The browser just loaded the earlier error free version.
