foreign_id request of rdio-US prevents response

Hi guys,

I've been building out an app which includes getting foreign_ids from Rosetta with EchoNest API.

My call is using the node API wrapper, but I have confirmed it works with out including 'id:rdio-US'.

Any thoughts as to why this might be happening?

Thanks in advance.

echo('catalog/read').get({
    format: 'json',
    id: id,
    bucket: [
        'id:7digital-US',
        'id:eventful',
        'id:facebook',
        'id:jambase',
        'id:rdio-US',
        'id:rhapsody-US',
        'id:seatgeek',
        'id:songkick',
        'id:spotify-WW',
        'id:twitter',
        'id:musicbrainz',
        'hotttnesss',
        'urls'
    ]
}, function(err, json) {

    if (err) {
        self.emit('error', err);
    } else {
        self.emit('loaded', json.response);
    }
});
