LocalStorage doesn't work

[YoniH]

When I set Storage: 'LocalStorage', my React page crashes on startup. The error is:

TypeError: this.storage.getItem is not a function CognitoAuth.getLastUser node_modules/amazon-cognito-auth-js/es/CognitoAuth.js:441 438 | CognitoAuth.prototype.getLastUser = function getLastUser() { 439 | var keyPrefix = 'CognitoIdentityServiceProvider.' + this.getClientId(); 440 | var lastUserKey = keyPrefix + '.LastAuthUser';

441 | var lastUserName = this.storage.getItem(lastUserKey); | ^ 442 | 443 | if (lastUserName) { 444 | return lastUserName;

My code:

import React, { Component } from 'react';
import { CognitoAuth } from 'amazon-cognito-auth-js';

const authData = {
    ClientId: '<my client id>',
    AppWebDomain: '<my domain>',
    TokenScopesArray: ['profile','openid'],
    RedirectUriSignIn: 'http://localhost:3000',
    RedirectUriSignOut: 'http://localhost:3000',
        UserPoolId: '<my pool id>',
        Storage: 'LocalStorage'
};

class App extends Component {
  constructor() {
    super();

    this.auth = new CognitoAuth(authData);

    this.handleSignIn = this.handleSignIn.bind(this);
    this.handleSignOut = this.handleSignOut.bind(this);
    this.test = this.test.bind(this);
  }

  handleSignIn() {
    this.auth.getSession();
  }

  handleSignOut() {
    this.auth.signOut();
  }

  test() {
    console.log(this.auth.isUserSignedIn());
    console.log(this.auth.getCurrentUser());
    console.log(this.auth.getSignInUserSession());
    console.log(this.auth.getUserContextData());
  }

  render() {
    return (
      <div>
        <button onClick={this.handleSignIn}>SignIn</button>
        <button onClick={this.handleSignOut}>SignOut</button>
        <button onClick={this.test}>Test</button>
      </div>
    );
  }
}

export default App;

Try it without specifying the storage type. by default, it will use localStorage if localStorage not available it will automatically use in memory storage. (if you need to understand how it works look at the implemntation of StorageHelper.js )

i. e remove this line Storage: 'LocalStorage'

Tried that already. When I do that, I see nothing in the local storage, even after I am redirected back to my page with id token and access token in the url. That's what made me explicitly specify LocalStorage in the first place
