Is there a full example of a bot that sends trade offers and then confirms using startconfirmationchecker as i always get this error once the method is called. Am i just missing something?   https://gyazo.com/a59aa36fed4a641325a926e41ccb890f 
steamClient.on('logOnResponse', function(logonResp) {
    if (logonResp.eresult === Steam.EResult.OK) {
        console.log('Logged in');
        steamFriends.setPersonaState(Steam.EPersonaState.Online);
        steamWebLogOn.webLogOn(function(sessionID, newCookie) {
            getSteamAPIKey({
                sessionID: sessionID,
                webCookie: newCookie
            }, function(err, APIKey) {
                offers.setup({
                    sessionID: sessionID,
                    webCookie: newCookie,
                    APIKey: APIKey
                });
                fetchtradeurl();
                offerItems();
                community.startConfirmationChecker(10000, identity_secret);
            });
        });
    }
});
