Uncaught TypeError: utag.link is not a function

[Kiddi]

I seem to be noticing a lot of error with out utag.js inject/implemention on out site. 
This uncaught error seem to occur everytime we reload a page.

This is in particular a problem as this interfer with the way we track videos.. 

We are using the async script, and have tried putting on head, body , bottom of body and top of body.. 
But nothing seem to give me a consistent result.. 

Somehow I can assure that this is will be created/executed at all time?

Hi @Kiddi,

Thanks for getting in touch. From your description, it seems that you are sending a tracking call before utag has completely initialised.

You could queue all events until utag is loaded. Credit to one of our former colleagues Brian Kranson for the following code:

//Inline on the page
(function(t,e,a,l,i,u,m){
    if(t.utag)return;e=t.utag={};e.e=[];
    e.view=function(a,b,c){e.e.push({a:a,b:b,c:c,d:"view"})};
    e.link=function(a,b,c){e.e.push({a:a,b:b,c:c,d:"link"})};
    e.track=function(a){e.e.push({a:a.data,b:(a.cfg?a.cfg.cb:null),c:(a.cfg?a.cfg.uids:undefined),d:a.event})};
}(window));

// Very first preloader code
// put the utag_events into the window scope as utag_events
// then delete utag so that the utag.js will build up as needed
(function(w){
    if(typeof w.utag !== 'undefined' && typeof w.utag.e === 'object'){
        w.utag_events = w.utag.e;
        delete w.utag;
    }
}(window))

// DOM Ready Extension
// loop through the window level array utag_events and call utag.track as necessary
// utag.track will use the view or link or any event as well as the callback or list of tag ids
(function(w){
    if((typeof w.utag_events === 'object' && w.utag_events.length > 0)){
        while(w.utag_events.length){
        d=w.utag_events.shift();
        (function(d){
            setTimeout(function(){
                utag.track({
                    event: d.d,
                    data: d.a,
                    cfg: {
                        cb: d.b,
                        uids: d.c
                    }
                });
            }, 150);
        })(d);
        }
    }
}(window))

Hope you find this useful.
