The last step of the tutorial about config.ts

Guys, no file like 'config.ts' exists in the whole project. Can anyone suggest, where else to make that connection between Ionic app and Cosmic JS custom bucket? (I followed the tutorial from: https://cosmicjs.com/blog/how-to-build-a-mobile-product-catalog-app-using-angular-js-ionic-and-cosmic-js)

export default {
  bucket: {
    slug: 'ionic-angular-app'
  }
}

I am getting the below error, on ionic serve

Error: Uncaught (in promise): TypeError: __WEBPACK_IMPORTED_MODULE_2_cosmicjs___default.a.getObjectType is not a function

Other details are as follows:


Ionic Framework: 3.9.2
Ionic App Scripts: 3.1.9
Angular Core: 5.2.10
Angular Compiler CLI: 5.2.10
Node: 8.11.1
OS Platform: Windows 10
Navigator Platform: Win32
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36

Any clues here?

Thanks in advance!
