Cannot call create from omise.schedules

I followed the documentation but got this error

omise.schedules.create({
    'every': 2,
    'period': 'day',
    'start_date': '2017-05-01',
    'end_date': '2018-05-01',
    'charge': {
        'customer': 'cust_test_57m2wcnfx96k634rkqq',
        'card': 'card_test_57m2w8iemdovs4f92m2',
        'amount': 100000,
        'description': 'Membership fee'
    }
}, function(error, schedule) {
    /* Response. */
});

TypeError: Cannot read property 'retrieve' of undefined
