Self describing events are not loaded

Hi Team,

I am new to snowplow and trying to generate some self describing events using javascript sdk and my pipeline is deployed in aws with postgres as target. Below are the steps I have followed
so far,
1> deployed aws pipeline with PG target
2> Created the schema for the self describing event and pushed to my iglu server using igluctl
3> initiated tracker in code with collector URL and
trying to pass the schema in self describing event following the below structure:

> 
> <script type="text/javascript" async=1>
>   ; (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", "https://cdn.jsdelivr.net/npm/@snowplow/javascript-tracker@3.17.0/dist/sp.js", "snowplow_tracker"));

But I don’t see the self describing event created or loaded in to the target and I don’t see any
error on console as well. Could you pls let me know If I am missing something. Happy to share more info if required.
