Wird error with Player Object

Am I missing something obvious? This works

const getPlayer = msg => getObj('player', msg.playerid).id;

and returns the proper id. But this does not:

const getPlayer = msg => getObj('player', msg.playerid).displayname;

In fact every property I've tried other than id returns an undefined value. Is this a bug or am I missing something silly?

Do you not have to use the get function for that property?

const getPlayer = msg => getObj('player', msg.playerid).get('displayname');

The only field on Roll20 Objects that is exposed as a property is id.  Everything else must be accessed via the .get() and .set() methods.

ah of course, thanks. I'm pretty rusty after a few months not touching the API.
