Property 'get' does not exist on type 'Credentials | CredentialsOptions'.

[akashbiz]

Hi, I am importing this library via npm and used Angular2 Cognito Quickstart for reference but I also need to use cognitosync library which get called immediately after login. Below is the code I am trying for which I am facing many issues

1. Property 'get' does not exist on type 'Credentials | CredentialsOptions'.
2. Property 'identityId' does not exist on type 'Credentials | CredentialsOptions'.
3. Property 'CognitoSyncManager' does not exist on type 'typeof ".../node_modules/aws-sdk/global"'.

---------cognito.service.ts--------- ` import { AuthenticationDetails, CognitoIdentityServiceProvider, CognitoUser, CognitoUserAttribute, CognitoUserPool } from "amazon-cognito-identity-js"; import * as AWS from "aws-sdk/global"; import * as STS from "aws-sdk/clients/sts"; import * as awsservice from "aws-sdk/lib/service"; import * as CognitoIdentity from "aws-sdk/clients/cognitoidentity";

buildCognitoCreds( idTokenJwt: string ) { let url = 'cognito-idp.' + Environment.REGION.toLowerCase() + '.amazonaws.com/' + Environment.USER_POOL_ID; if ( Environment.COGNITO_IDP_ENDPOINT ) { url = Environment.COGNITO_IDP_ENDPOINT + '/' + Environment.USER_POOL_ID; } let logins: CognitoIdentity.LoginsMap = {}; logins[url] = idTokenJwt; let params = { IdentityPoolId: Environment.IDENTITY_POOL_ID, Logins: logins }; let serviceConfigs: awsservice.ServiceConfigurationOptions = {}; if ( Environment.COGNITO_IDENTITY_ENDPOINT ) { serviceConfigs.endpoint = Environment.COGNITO_IDENTITY_ENDPOINT; } let creds = new AWS.CognitoIdentityCredentials( params, serviceConfigs ); this.setCognitoCreds( creds ); return creds; }

authenticate( username: string, password: string ): Promise {

let authenticationData = {
	Username: username,
	Password: password,
};
let authenticationDetails = new AuthenticationDetails( authenticationData );

let userData = {
	Username: username,
	Pool: this.getUserPool()
};
let cognitoUser = new CognitoUser( userData );
var self = this;
return new Promise(
	( resolve, reject ) => {
		cognitoUser.authenticateUser( authenticationDetails, {
			onSuccess: function( result ) {
				let creds = self.buildCognitoCreds( result.getIdToken().getJwtToken() );
				console.log(creds);
				AWS.config.credentials = creds;
				let clientParams: any = {};
				if ( Environment.STS_ENDPOINT ) {
					clientParams.endpoint = Environment.STS_ENDPOINT;

Please help.

You should use new AWS.CognitoSync() instead of new AWS.CognitoSyncManager().

This blog post walks through the setup and example of using the Cognito Sync JavaScript library. It can help you with errors you are facing.

Thanks for response @chetanme, I will try it out and get back to you with results.

The following might help for your first issue. let creds:AWS.CognitoIdentityCredentials = new AWS.CognitoIdentityCredentials(params);

   ` console.log("creds",creds);

    creds.get(function(err) {
      if (err) return console.log("Error", err);
      else {
        console.log("Sucuessfully ");
       console.log("Cognito Identity Id", creds.identityId);
       console.log("token",creds.sessionToken);
      }
    });```
