getting the OTP is invalid

[thatkookooguy]

I changed the code in the test.js a little bit to include client_id and secret_key. Here's the code:

#!/usr/bin/env node

const
stdin = process.stdin,
stdout = process.stdout,
client_id = '<client_id>',
secret_key = '<secret_key>';

var Yubikey = require('./lib/yubikey');

var yubikey = new Yubikey(client_id, secret_key);

function verify(otp) {
  yubikey.verify(otp, function(err) {
    if (err) {
      stdout.write(err + "\n");
    } else {
      stdout.write("Success!  Your token was verified.\n");
    }
    process.exit(0);
  });
}

function readOTP() {
  stdin.resume();
  stdout.write("YubiKey OTP: ");
  stdin.once('data', function(buf) {
    verify(buf.toString().trim());
  });
}

if (!module.parent) {
  readOTP();
}

I keep getting the error

Error: The OTP is invalid.

any idea what I'm doing wrong?

thanks
