user.on('error') returns sometimes empty object

[MrPotato]

user.on('error', function(e) {

    log(username, "error: " + JSON.stringify(e));

    log(username, e);

});

 

Sometimes returns "{}"

 

log:

[y6p123] error:  {}

[y6p123] }

Why?

e is an Error object. Calling JSON.stringify on an Error object returns {}.
