No response or error is coming when I try to schedule a meeting via Skype web sdk

I'm trying to schedule a meeting using the skype sdk. I've given the code same as shown in the samples. But I'm not getting any errors or any response from the code to schedule meeting. Please go through the codes and let me know if there is any errors in the code below. I'm stuck with this

    $('#authentication').click(function() {
        var client_id = "xxxxxx-xxxx-xxxx-xxxx-xxxxxxxx";
        window.sessionStorage.setItem('client_id', client_id);
        var href = 'https://login.microsoftonline.com/common/oauth2/authorize?response_type=token&client_id=';
        href += client_id + '&resource=https://webdir.online.lync.com&redirect_uri=' + window.location.href;
        window.location.href = href;
    });
    $('#createmeeting').click(function() {
        var client;
        var conversation;
        var Application;
        console.log(sessionStorage.getItem('client_id'));
        Skype.initialize({ apiKey: 'a42fcebd-5b43-4b89-a065-74450fb91255' }, function (api) {
            Application = api.application;
            client = new Application();
            console.log('client created');
            var meeting = client.conversationsManager.createMeeting();
            meeting.subject('Planning meeting');
            meeting.expirationTime(new Date + 24 * 3600 * 5);
            meeting.onlineMeetingUri.get().then(uri => {
               var conversation = client.conversationsManager.getConversationByUri(uri);
               console.log(';'); // even this is not showing 
            }, function (error) {
                console.log(error);
            });
                 console.log(conversation);

        }, function (err) {
            console.log(err);
            alert('Cannot load the SDK.');
        });            
    });
