exports.transportSecurityDecryption = async function mmTransportSecurityDecryption(dataToReceive, keys) {
  const JSEncrypt = require('node-jsencrypt');
  const CryptoJS = require("crypto-js");

  // Asymmetrically decrypt symmetric cypher data with server private key
  const privateKeyQuery = new Parse.Query("ServerPrivateKey");
  const keyQueryResult = await privateKeyQuery.find({useMasterKey: true});
  const object = keyQueryResult[0];
  const serverPrivateKey = object.get("key");
  const crypt = new JSEncrypt();
  crypt.setPrivateKey(serverPrivateKey);
  let decryptedDataString = crypt.decrypt(keys);
  let decryptedData = JSON.parse(decryptedDataString);

  // Symmetrically decrypt transit data
  let symmetricKey = decryptedData.symmetricKey;
  let symmetricNonce = decryptedData.symmetricNonce;
                                                        // Works perfectly till here <---
  var decrypted = CryptoJS.AES.decrypt(

    CryptoJS.enc.Utf8.parse(symmetricKey),
    {iv: CryptoJS.enc.Hex.parse(symmetricNonce)}
    );
  return decrypted.toString(CryptoJS.enc.Utf8);
