Amphtml: amp-install-serviceworker scope error

[meistudioli]

To whom it may concern:

I use amp-install-serviceworker for a while and it works fine. But I found an error occurred.

The path of the provided scope ('/') is not under the max scope allowed ('/mei/'). Adjust the scope, move the Service Worker script, or use the Service-Worker-Allowed HTTP header to allow the scope.

Here comes some information.

• demo site: https://blog.lalacube.com/mei/yahoo_auction_fp_amp.php
• service-worker file path: https://blog.lalacube.com/mei/sw_yauc_amp_workbox.js

it should work well in scope ./

I checked the amp-install-serviceworker code. Looks like something strange here.

I wonder is this an issue or should I need to do anything ?

Right, I see the big in defaulting it to /.
While we fix this, you can add data-scope="/me" to amp-install-serviceworker for now.
