 * TypeError: Failed to update a ServiceWorker for scope (‘[https://n*****os.io/&#8217](https://n*****os.io/&#8217);)
   with script (‘[https://n*****os.io/superpwa-sw.js&#8217](https://n*****os.io/superpwa-sw.js&#8217);):
   An unknown error occurred when fetching the script.

 * İ also get this error:
 * Warnings: Lighthouse couldn’t read the `start_url` from the manifest. As a result,
   the `start_url` was assumed to be the document’s URL. Error message: ‘ERROR: 
   start_url must be same-origin as document’.

 * Can you please change the start page to something other from the dropdown over
   the superpwa settings page and try it out again? Mostly, this error occurs if
   the scope is beyond the start page URL.
