Using sneurlax/monerojs and I'm having a problem connecting to wallet

Question

Here is my code:

const Monero = require('monerojs');

var daemonRPC = new Monero.daemonRPC({ autoconnect: true })
.then((daemon) => {
    daemonRPC = daemon; // Store daemon interface in global variable

    const walletRPC = new Monero.walletRPC() // Connect with defaults
    .then(wallet => {
        walletRPC = wallet;
        walletRPC.create_wallet('monero_test_wallet', '')
        .then(new_wallet => {
            walletRPC.open_wallet('monero_test_wallet', '')
            .then(wallet => {
                walletRPC.getaddress()
                .then(balance => {
                    console.log(balance);
                })
                .catch(err => {
                    console.error(err);
                });
            })
            .catch(err => {
                console.error(err);
            });
        })
        .catch(err => {
            console.error(err);
        });
    });
})
.catch(err => {
    throw new Error(err);
});

And my error:

(node:8373) UnhandledPromiseRejectionWarning: Failed to autoconnect to wallet
(node:8373) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)
(node:8373) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

I'm a newbie, so help would really be appreciated. Thank you so much in advance!

As you are not specifying the wallet details (port, host etc), that library uses the defaults:

class walletRPC {
  constructor(hostname = '127.0.0.1', port = 28083, user = undefined, pass = undefined, protocol = 'http', network = 'mainnet') {

Therefore, you would need to have started the monero-wallet-rpc, on the same host, with something like:

monero-wallet-rpc --rpc-bind-port 28083 \
    --disable-rpc-login --wallet-file your-wallet --password your-password

Or to start without an initial wallet like:

monero-wallet-rpc --rpc-bind-port 28083 \
    --disable-rpc-login --wallet-dir /some/path
