I am getting an error whenever I use the javascript tracker. The error is in line 54, Column 672 on the following call:
E.send(g.stringify(A))
The error message is
sp.js - Uncaught InvalidStateError: Failed to execute 'send' on 'XMLHttpRequest': The object's state must be OPENED.q @ sp.js:onreadystatechange @ sp.js
Here is my initialization code:
<!-- Snowplow starts plowing -->
<script type="text/javascript">
(function () {
;(function(p,l,o,w,i,n,g){if(!p[i]){p.GlobalSnowplowNamespace=p.GlobalSnowplowNamespace||[];
p.GlobalSnowplowNamespace.push(i);p[i]=function(){(p[i].q=p[i].q||[]).push(arguments)
};p[i].q=p[i].q||[];n=l.createElement(o);g=l.getElementsByTagName(o)[0];n.async=1;
n.src=w;g.parentNode.insertBefore(n,g)}}(window,document,"script","//d63r508qjur44.cloudfront.net/2.4.1/sp.js","spvb"));
window.spvb('newTracker', 'co', 'tracking.viewbix.com', { // Initialise a tracker
appId: 'az-viewbix-player', // Application ID can be anything you want
platform: 'web', // Do not change
post: true, // Use POST rather than GET
bufferSize: 1, // Wait for 5 events to be recorded then send them all into Snowplow via a single POSTS request. You can set this to whatever you want - if you don't set it it will defuault to 1
cookieName: "_vbtrck_" // Name the viewbix cookie. This will prevent another Snowplow tracker writing to the same cookie, e.g. if a Viewbix ad unit is shown on a publisher site where Snowplow is running
});
}());
</script>
<!-- Snowplow stops plowing -->
We call the tracker like this:
window['spvb'](
'trackUnstructEvent', {
'schema': mySchema
, 'data': myData}
, myContexts);
Please help.
