const axios = require('axios');
// import axios from "axios";

  res => res,
  err => {
    // Any HTTP Code which is not 2xx will be considered as error
    const statusCode = err.response.status;
    if (statusCode === 401 || statusCode === 403) {
      window.location = '/login';

    throw err;
