Error on PageModule When using AWS Polly

Hello, I ran into GuidesPageModule Not Found error when trying to use Amazon AWS Polly SDK. Once i remove Amazon Polly the page works again. What could be the conflict between my page module and Polly SDK? Please help. Thanks.

Here is my service code:

import { Injectable } from '@angular/core';
import polly from 'aws-sdk/clients/polly';


declare var require: any;
const xmlbuilder = require('xmlbuilder');
// const AWS = require('aws-sdk');

@Injectable({
  providedIn: 'root'
})
export class TtsService {
 polly: any;
  constructor() {
  }

 async  convXml(text: string) {
    const xml_body = xmlbuilder.create('speak')
    .ele('prosody')
    .att('volume', 'loud')
    .att('rate', '90%')
    .att('pitch', 'medium')
    .txt(text)
    .end();
  // Convert the XML into a string to send in the TTS request.
  console.log(xml_body.toString());
  // Create an Polly client
  this.polly = new polly();
  const params = {
    'Text': xml_body.toString(),
    'TextType': 'ssml',
    'OutputFormat': 'mp3',
    'VoiceId': 'Amy',
    'LanguageCode': 'en-US'
  };
  await this.polly.synthesizeSpeech(params, (err, data) => {
    if (err) {
        console.log(err.code);
    } else if (data) {
      console.log(data);
        if (data.AudioStream instanceof Buffer) {
        }
    }
  });

  }
}

Initializing my Service on component page it stops working.

 constructor( private ttsService: TtsService) {
  }
