global.util.crypto.lib.randomBytes is not a function error

Question

I am new to react. I am getting the following error while error while using amazon-cognito-identity-js npm package which states as follows

_global.util.crypto.lib.randomBytes is not a function

My Actions file in react is as follows

    import axios from 'axios';
    import * as actionTypes from './actionTypes';
    import authenticateUser from '../services/cognitoAuthenticateUser';
    import {reset} from 'redux-form';


    const signInUserSuccess = ({...result,email, newPasswordRequired = false}) => {
      return {
        type: actionTypes.SIGNIN_SUCCESS,
        ...result,
        email
      }
    };

    const signInUserFailure = (error) => {
      return {
        type: actionTypes.SIGNIN_FAILURE,
        error
      }
    };


    /* Login a given user based on his credentials added */
    export function LoginFeature(email,password,callback){

      return (dispatch) => {
        authenticateUser(email, password)
         .then(result => {
                          //console.log(result);
                          dispatch(signInUserSuccess({...result, email}));
                          callback();
                          dispatch(reset('loginForm'));
                          })
         .catch(e => {
           dispatch(signInUserFailure(e.message));
           dispatch(reset('loginForm'));
         })
      }
    }

My User Authenticate service file is as follows

import {
    AuthenticationDetails,
    CognitoUserPool,
    CognitoUser} from "amazon-cognito-identity-js";

  import {Config} from "aws-sdk";


  import awsConfig from "../../configs/aws-incognito-credentials";

  /*Credentails for AWS Incognito usage*/
  Config.region = awsConfig.region;

  const userPool = new CognitoUserPool({
    UserPoolId: awsConfig.UserPoolId,
    ClientId: awsConfig.ClientId
  });

  // Use case 4. Authenticating a user and establishing a user session with the Amazon Cognito Identity service.
  export const authenticateTheGivenUser = (username, password) => {
    return new Promise(function (resolve, reject) {

      const user = new CognitoUser({ Username: username, Pool: userPool })
      const authenticationData = { Username: username, Password: password }
      const authenticationDetails = new AuthenticationDetails(authenticationData)

      user.authenticateUser(authenticationDetails, {
        onSuccess: result => {
          console.log(result);
          resolve({...result, newPasswordRequired: false})
        },
        onFailure: err => reject(err),
        newPasswordRequired: (userAttributes, requiredAttributes) => resolve({newPasswordRequired: true})
      })
    })
  }

  export default authenticateTheGivenUser;

My package.json file is as follows

I am unable to understand why I am getting this error? Can somebody point as to what am I doing wrong?

Answer 1

Downgrading aws-sdk gets rid of the problem:

yarn add [email protected]

For me aws-sdk is a dependency of aws-amplify and got automatically updated, after that I started seeing the same error.
