AES-CTR decryption

I'm having problems decoding specific AES messages.

Used this site for testing... AES Encryption: Encrypt and decrypt online — Cryptii - result of encrypting (4d 65 73 73 61 67 65 = 4a 9b 9c 07 80 b2 66)

Algorithm: AES-128
Mode: CTR
Key: 000102030405060708090a0b0c0d0e0f
IV: 101112131415161718191a1b1c1d1e1f

Key and IV from here... CryptoJS - CryptoJS

Here is my code from Node-RED...

var cryptojs =;

var key = '000102030405060708090a0b0c0d0e0f';
var iv = '101112131415161718191a1b1c1d1e1f';
var data = msg.payload;

var message = cryptojs.AES.decrypt(
    key, { 
        mode: cryptojs.mode.CTR, 
        iv: iv }

msg.payload = message.toString();

return msg;

Decrypting 4a 9b 9c 07 80 b2 66 return "" from a debug node.

I feel like the format (HEX) of the imput might be a problem.
