ruby on rails - Soundcloud Embed: Uncaught TypeError: Layer must be a document node -

-

i have rails app uses embedded soundcloud players. player loaded in iframe includes basic rails view containing html used load player:

<iframe width="100%" height="300" scrolling="no" frameborder="no" src="https://w.soundcloud.com/player/?url=<%= @id %>&amp;auto_play=false&amp;hide_related=false&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false&amp;visual=true"></iframe>

every , then, when loading site, player fails render , following error: 

uncaught typeerror: layer must document node  d          @ widget-6dc4a288.js:21

we tried replacing raw html js code sc sdk, still experienced same error:

<script src="//connect.soundcloud.com/sdk-2.0.0.js"></script> <script>   sc.initialize({     client_id: "<%= secret_key %>"   });   sc.oembed("<%= @id %>", {auto_play: true, height: 300}, function(oembed){     document.getelementbyid('video-container').innerhtml = oembed.html;   }); </script>

does know source of error? seems occur 1/4 times try render sc player.
