I'm trying to get the lazy loaded iframe Id and fail with a TypeError n is null. What am I missing?
$(document).ready(function() {
var widgetIframe = document.getElementById('sclazy');
console.log(widgetIframe);
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.0/jquery.min.js"></script><iframe id="sclazy" height="500" width="500" frameborder="0" allow="autoplay" class="lazyload" allowfullscreen="" data-src="https://w.soundcloud.com/player/?url=https://api.soundcloud.com/tracks/188612777&auto_play=false&buying=false&sharing=false&download=true&single_active=true&hide_related=true&show_comments=true&show_user=false&show_reposts=false&show_teaser=false&visual=true&show_artwork=true"></iframe>
