First argument must be a Buffer (msgpack + forge aes encryption)

[carlosjpr-collab]

I am trying to excute this code that do

• read json file

• change json to message pack

• encrypt the new json

• decypt the new json

• change json message pack to normal json (here is my error)

var fs = require('fs');
var forge = require('node-forge');
var msgpack = require('msgpack');

file = []
x= null
fs.readFile(process.cwd() + "/test.json", function(err, data)
{
  file  = data
  // json = JSON.stringify(JSON.parse(file),null,2);
  packedFile = msgpack.pack(file)
  key = 'SdI6qAn1602f942'

  // encrypt some bytes using ECB mode
  var cipher = forge.cipher.createCipher('AES-ECB', key);
  cipher.start();
  cipher.update(forge.util.createBuffer(packedFile));
  cipher.finish();
  var encrypted = cipher.output;

  // decrypt some bytes using ECB mode
  var decipher = forge.cipher.createDecipher('AES-ECB', key);
  decipher.start();
  decipher.update(encrypted);
  decipher.finish(); // check 'result' for true/false
  // outputs decrypted
  console.log(msgpack.unpack(decipher.output.data)) 
});

But I am getting this error in this line:

console.log(msgpack.unpack(decipher.output.data)) 
Uncaught TypeError: First argument must be a Buffer

My test file is any json file

{
"testin": "test"
}
