Rollbar plugin - ios build failed

Just to be clear, i am using 2 types of rollbar notifications: first one is releated to the plugin to catch native Android/IOS errors, and the socond one to catch JS errors (import { RollbarModule } from 'angular-rollbar):

app.module.ts:

import { Rollbar } from '@ionic-native/rollbar'; // catch native errors
import { RollbarModule } from 'angular-rollbar'; // catch JS errors

@NgModule({

  imports: [
...
    RollbarModule.forRoot({
            accessToken: 'TOKEN'
        }),
  ],

providers: [
...
   Rollbar

  ],
})

Back to the plugin issue, i am trying to remove/add plugin without success so far

ionic cordova build ios --prod --verbose:
