{{ROOT_URL}} (for registration) not getting replaced during build

all I have is this (in my ember-cli-config):

    'ember-service-worker': {  },

but in the output, I’m getting:

(function(){"use strict"
function n(n){e.push(n)}var e=[],r=[]
"serviceWorker"in navigator&&navigator.serviceWorker.register("{{ROOT_URL}}sw.js",{scope:"{{ROOT_URL}}"}).

@stukalin how good are you at debugging rollup builds? https://github.com/DockYard/ember-service-worker/pull/130 😄

Tried to upgrade the Ember from v3.4 to 3.5 today and received the same issue… Looking forward to see a fix
