Im trying to utilize AWS JS SDK in my Angular application.

Consider the following code:

import * as AWS from 'aws-sdk';
import Component, OnInit from '@angular/core';

declare let AWSCognito: any;

@Component(
 selector: 'app-root',
 templateUrl: './app.component.html',
 styleUrls: ['./app.component.css']
)

export class AppComponent implements OnInit 

 private _dynamodb;

 constructor() 
 AWS.config.region = 'eu-west-2'; // Region
 AWS.config.credentials = new AWS.CognitoIdentityCredentials(
 IdentityPoolId: 'eu-west-2:xxyyzz'
 );
 this._dynamodb = new AWS.DynamoDB.DocumentClient();
 

 ngOnInit() 
 this._dynamodb.get(TableName: 'somename', Key: projectId: 123321, (err, data) => 
 )
 

When the above code is executed the following error appears:

ERROR TypeError: Cannot convert undefined or null to object

I can see that it's this._dynamodb.get that makes the system crash.

Any idea what I'm doing wrong?

EDIT:

Full stack trace:
