Whatsapp clone with ionic2 CLI not running on emulator

Hi !
I’ve started this meteor tutoriel with ionic2 CLI https://angular-meteor.com/tutorials/whatsapp2/ionic/meteor-server-side .
Everything is fine, but when I reached step 4 (the one where we add meteor server), the app won’t work on emulator (it does run on browser).
When I checked the console, it gives this error
Uncaught ReferenceError: __meteor_runtime_config__ is not defined

Did someone got it working? if yes, please share with us the steps.
