hostname issue

var isLocalhost=Boolean(window.location.hostname==="localhost"||// [::1] is the IPv6 localhost address.

TypeError: Cannot read property 'hostname' of undefined

That code is in src/serviceWorker.js, which is unchanged from the original. It’s only executed in the browser so I don’t know how window.location could be undefined (especially if window is not undefined).

Can you provide more info about how you came across this error?
