Getting not-authorized error when using valid user with ejabberd

Hi,

I am in the process of upgrading node-xmpp-client to xmppjs. After doing so, I am no longer able to authenticate with my xmpp host, ejabberd and am getting the error: "SASLError: not-authorized - Invalid username or password".

Below is the code from the tutorial that I am currently troubleshooting. The only thing that I changed is the parameters passed into the client method:

const { client, xml } = require('@xmpp/client')
const debug = require('@xmpp/debug')

process.env.NODE_TLS_REJECT_UNAUTHORIZED = 0

// Start of changed code
const xmpp = client({
    service: 'wss://localhost:5443/ws',
    domain: 'localhost',
    username: 'admin@localhost',
    password: 'admin',
})
// End of changed code

debug(xmpp, true)

xmpp.on('error', (err) => {
    console.error(err.message)
})

xmpp.on('offline', () => {
    console.log('offline')
})

xmpp.on('stanza', async (stanza) => {
    if (stanza.is('message')) {
        await xmpp.send(xml('presence', { type: 'unavailable' }))
        await xmpp.stop()
    }
})

xmpp.on('online', async (address) => {
    // Makes itself available
    await xmpp.send(xml('presence'))

    // Sends a chat message to itself
    const message = xml('message', { type: 'chat', to: address }, xml('body', {}, 'hello world'))
    await xmpp.send(message)
})

xmpp.start().catch(console.error)

And below are the logs:

I made sure that the user was still valid and that the endpoint in ejabberd I am pointing the client to exists an is running.

Is this a bug (probably not I think)?
