I fixed this error by installing babel-polyfill

npm install babel-polyfill --save

then I imported it in my app entry point

import http from 'http';
import config from 'dotenv';
import 'babel-polyfill';
import { register } from 'babel-core';
import app from '../app';

for testing I included --require babel-polyfill in my test script

"test": "export NODE_ENV=test|| SET NODE_ENV=test&& mocha --compilers 
  js:babel-core/register --require babel-polyfill server/test/**.js --exit"
