Why can't web crypto decrypt, but aykxt/crypto can?

[iugo]

base64 data:

const keyStr = 'AVLbWeQ3zMdfpVVF6kFsZ9E4ODL1wjjykB5ifzjLPft';
const dataStr = 'Yy5XCfHFvIH+UZC+MrSDH1ZMGwF+uAnxDW5i8g5LSD5FQPAdFja9mfy9eZ1rn223cg5PRaJc2dbaRIqWbR2GwKtjxfvDJBv9R3cP5NIx+HADSlSvEr3w9a5QmjPfzZK0';

Node.js code:

function decryptWithoutFinal(encrypted, aesKey) {
  const iv = aesKey.slice(0, 16);
  const crypto = Crypto.createDecipheriv("AES-256-CBC", aesKey, iv);
  let decrypt = crypto.update(encrypted, "base64");
  return decrypt.toString();
}

function decryptWithFinal(encrypted, aesKey) {
  const iv = aesKey.slice(0, 16);
  const crypto = Crypto.createDecipheriv("AES-256-CBC", aesKey, iv);
  let decrypt = crypto.update(encrypted, "base64");
  decrypt += crypto.final('utf8');
  return decrypt;
}

Deno code:

async function decryptAESCBC(keyStr: string, dataStr: string) {
  const u8aKey = decode(keyStr);

  const key = await crypto.subtle.importKey(
    'raw',
    u8aKey,
    {
      name: 'AES-CBC',
    },
    false,
    ['encrypt', 'decrypt']
  );

  const res = decode(dataStr);

  const iv = u8aKey.slice(0, 16);
  const d = await crypto.subtle.decrypt(
    {
      name: 'AES-CBC',
      iv,
    },
    key,
    res
  );

  return new Uint8Array(d);
}

function decryptByC(keyStr: string, dataStr: string) {
  const key = decode(keyStr);
  const iv = key.slice(0, 16);

  const decipher = new Cbc(Aes, key, iv);
  const decrypted = decipher.decrypt(decode(dataStr));

  return decrypted;
}
