Using Stellar-SDK ionic serve works, cordova build doesnt

Ionic Framework
1

Hello! Im trying to build an app using Ionic 4 that connects to Stellar blockchain network. In order to do so I import js-stellar-sdk into my Ionic app.

I can use “ionic serve” and everything works fine, but when I try to test the app with an android emulator using “ionic cordova run android” or “ionic cordova build android” I get the error:

Error

ERROR in ./node_modules/eventsource/lib/eventsource.js
Module not found: Error: Can't resolve 'http' in 'C:\Users\Rafael Cisneros\Desktop\Work\Ionic\StellarTest\node_modules\eventsource\lib'                                                                                                         ERROR in ./node_modules/eventsource/lib/eventsource.js
Module not found: Error: Can't resolve 'https' in 'C:\Users\Rafael Cisneros\Desktop\Work\Ionic\StellarTest\node_modules\eventsource\lib'
[ERROR] An error occurred while running subprocess ng.

If I comment the line where I use stellar, build runs successfully:

this.server = new Server('https://horizon-testnet.stellar.org');

I pushed it into a repo:
