In case it helps anyone, changing it to this works:
twitch.getChannel('highstakespoke', function(err, results) {
if(err) console.log(err);
console.log(results);
});
But if you do this:
request.get({
url: 'https://api.twitch.tv/kraken/channels' + '/highstakespoke',
json: true
}, function(err, response, body) {
if(err) console.log(err);
console.log(response.statusCode);
You will get 200 and 400 randomly.
