HTML error inside client, but still runs?

I get expression expected in my client/template/test.html in Meteor, but it still manages to run?

Meteor.call('addTestTicket', userid, date_start, date_end, (error, data) => {
                    if (error) {
                        Bert.alert('Please login before trying to submit!', 'danger', 'growl-top-right', 'fa-frown-o');
                    } else {
                        Bert.alert({title: 'Test Sent', message: 'now in queue', type: 'info', style: 'growl-top-right', icon: 'fa-music'});
                        Meteor.setTimeout(function(){window.location.href = '/';}, 3000);
                        console.log('the added ticket is : ', data); }
                }); <!-- End of Meteor.call -->

server.js:

Meteor.methods({

    addTestTicket: function (text, start_date, end_date) {
        if (!Meteor.userId()) {
            //Add Bert notification here?
            //Bert.alert('Please login before submitting', 'danger', 'fixed-top', 'fa-frown-o');
            throw new Meteor.Error('Not authorized');
        }

        //Generate random fake tickets TESTxxxxx
        var fakeTicketNo = Random.hexString(6);
        console.log('Random TicketNo is : ', fakeTicketNo);

        FutureTasks.insert({
            userid: text, '
            assigned_to: 'Testing',
            number: ''.concat("TEST", demoTicketNo), 
            assignment_group: 'Test',
            start_date: start_date,
            end_date: end_date,
            count: 0
        });
