I'm trying to use the following funciton to encrypt a Base64 encoded string using the AES-256-CFB algorithm, and when I try to encode the result back to Base64 it casues the following error: Uncaught TypeError: r.clamp is not a function

function (base64EncodedString, password) {
    let iv = CryptoJS.lib.WordArray.random(256 / 16);

    let salt = CryptoJS.enc.Hex.parse(iv.toString(CryptoJS.enc.Hex).substr(0, 16));

    let key = CryptoJS.EvpKDF(password, CryptoJS.enc.Hex.parse(salt), { keySize: 256 / 32 });

    let nonEncryptedString = CryptoJS.enc.Base64.parse(base64EncodedString);

    let cipher = CryptoJS.lib.CipherParams.create({ ciphertext: nonEncryptedString , iv: iv, salt: salt, mode: CryptoJS.mode.CFB, padding: CryptoJS.pad.NoPadding,});
    
    let encrypted = CryptoJS.AES.encrypt(cipher, key, {mode: CryptoJS.mode.CFB, padding: CryptoJS.pad.NoPadding, iv: iv});
        
    let ecrytpedBase64 = CryptoJS.enc.Base64.stringify(encrypted);
    
    return ecrytpedBase64;
};
