Extra config in app.module.ts import fails with aot compiler error

Hi,

I give a try on new AWS template from https://github.com/ionic-team/ionic2-starter-aws, everything looks great.
However, when I try to build prod release by ionic cordova build android --prod --release, error like below appears.

I assume the error roots from here IonicModule.forRoot(MyApp, new AwsConfig().load()) in app.module.ts and it is related to AOT compiler feature. But I haven't found fix on this.

Anybody has any hint?

Thanks,
Xi

app.config.ts with AwsConfig defined

import { Injectable } from '@angular/core';

declare var AWS: any;
declare const aws_mobile_analytics_app_id;

declare const aws_cognito_identity_pool_id;
declare const aws_user_pools_id;

declare const aws_user_files_s3_bucket;

@Injectable()
export class AwsConfig {
  public load() {

    // Expects global const values defined by aws-config.js
    const cfg = {
      "aws_mobile_analytics_app_id": aws_mobile_analytics_app_id,

    };

    AWS.config.customUserAgent = AWS.config.customUserAgent + ' Ionic';

    return cfg;
  }
}
