Hi Team, I am using this module(amazon-cognito-identity-js) for my react project(with webpack), This module is creating issue in the production build.

Uncaught TypeError: Cannot set property 'createCredentials' of undefined

Hi, I have a temporary fix to this issue.(but, This might cause side effects)

Need to make changes in file: node_modules\aws-sdk\node_modules\crypto-browserify\index.js

changes: comment the following code snippet in the above mentioned file.

each(['createCredentials'
, 'createCipher'
, 'createCipheriv'
, 'createDecipher'
, 'createDecipheriv'
, 'createSign'
, 'createVerify'
, 'createDiffieHellman'
, 'pbkdf2'], function (name) {
  exports[name] = function () {
    error('sorry,', name, 'is not implemented yet')
  }
})

I am working to find permanent fix to this issue. Any help will be appreciated.
