I am using the polymer-starter kit for my app and tried building it. When opening the index.html of the builded app the my-app.html is missing. I didn't change any files in the starter kit, and the problem also appears.
Steps to Reproduce
Create an application project: polymer init --> select polymer-starter-kit Build: polymer build Try viewing index.html
This is what I get in the console:
/src/my-app.html Failed to load resource: net::ERR_FILE_NOT_FOUND
webcomponents-loader.js Failed to load resource: net::ERR_FILE_NOT_FOUND
index.html:1 Uncaught (in promise) DOMException: Failed to register a ServiceWorker: The URL protocol of the current origin ('null') is not supported.
