Decrypt function can't read content hash throws : TypeError [ERR_INVALID_ARG_TYPE]:

Question

When I first tested it both the encrypt and decrypt using the aes-256-ctr algorithm worked fine but after I posted it to IPFS and returned it it gave me the following error.

TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be of type string or an instance of Buffer, ArrayBuffer, or Array or an Array-like Object. Received undefined

It all looks up to par for me. Here is the encryption.js file.

const crypto = require('crypto');
const algorithm = 'aes-256-ctr';
const secretKey = 'vOH6sdmpNWjRRIqCc7rdxs01lwHzfr33';
const iv = crypto.randomBytes(16);
//const file = fs.readFileSync("test.txt");
//console.log(secretKey.length);
const encrypt = (text) => {
  const cipher = crypto.createCipheriv(algorithm, secretKey, iv);
  const encrypted = Buffer.concat([cipher.update(text), cipher.final()]);
  return {
    iv: iv.toString('hex'),
    content: encrypted.toString('hex')
  };
};
const decrypt = (hash) => {
  const decipher = crypto.createDecipheriv(algorithm, secretKey, Buffer.from(hash.iv, 'hex'));
  const decrypted = Buffer.concat([decipher.update(Buffer.from(hash.content, 'hex')),
    decipher.final()]);
  return decrypted.toString();
};

It seems to work for me -- but only if you pass the entire object returned by encrypt into decrypt. If you just pass in the hash without the iv, you get that error.
