just basically trying to log the title, artist and track duration but getting the following log in console:
Error in script: TypeError: Cannot access member 'title' of undefined
And here is the code:

registerPlugin({
    name: 'Testing',
    version: '1.0',
    description: 'Testing',
    author: 'Alw3ys <[email protected]>',
    vars: {},
    autorun: true
}, function(sinusbot, config) {
    var event = require('event');
    event.on('track', function(trackEvent) {
        var engine = require('engine');
        var track = trackEvent.track;
        engine.log(track.title() + '\n' + track.artist() + '\n' + String.valueOf(track.duration()));
    });
});

I'm pretty sure artist and trackduration will use return me the following error but is unreachable at the moment.

I just wanna know what do I should istead of trackEvent.track.title() to get the track title.

flyth already responded in the chat:
trackEvent is already the track.

Edit: so try just using: trackEvent.title() instead of trackEvent.track.title()
