simple question about .first()

[tacman]

I'm still struggling with Promises.

What am I doing wrong here? It seems so simple, but I'm fighting. count works, first doesn't.

        db.tables.forEach(t=>{
            t.count(c => console.error('count of ' + t.name + ' is  ' + c));
            t.first(item => console.error(item));
            t.first()
                .then(item => console.error(item))
                .catch(err => console.error(err))
                .finally(() => console.log('finally!'))
        });

I'm not even sure how to debug this. Sorry for such a simple question. Thanks!
