Ember-Electron: Uncaught Error: Expected to find: 'service:settings

I am trying to run an open source ember-electron project: https://github.com/nano-wallet-company/nano-wallet-desktop

But it gives me the error shown in image below though I have it in my code. The same source worked back before 2 months but now it doesnt. May be there are upgrades in ember-cli I guess.

Can anyone tell me what can be the issue?

Please ignore red spots, I have renamed the repo but it is a fork of nano wallet.

Issue:
