Figure out the problem with Service Workers

[jonrh]

I believe I have found the problem that blocks me from publishing the website.

HTTP local dev

No errors appear when developing locally.

HTTP, works correctly

When the site is tested on HTTP: http://dev.jonrh.is.s3-website-us-east-1.amazonaws.com/

HTTPS, does not work

When the site is tested on HTTPS: https://dev.jonrh.is/

The Problem

I suspect that something is broken with the plugin gatsby-plugin-offline. On HTTP Chrome alerts that since the service worker does not have a HTTPS origin it was blocked. Then the site works as expected. However when HTTPS is used there seems to be some error in the service worker and you can not switch between pages.

One way to solve this temporarily would be to try to disable or remove the gatsby-plugin-offline plugin.

Fixed in commit d3662d3.

Removed gatsby-plugin-offline. Had to invalidate the CloudFront edge cache and reset Chrome and FireFox pretty hard. Getting rid of cached service workers, sw.js, in browsers is hard. First you have to clear the cache, then you also have to restart the browser. Had to do this in both FireFox and Chrome.
