Youtube Unsafe JavaScript is trying to access a frame with a URL

Here I have another question, this time about the youtube API. I use this code to get youtube player:

<div id=\"youtubeVideoContainer\"></div><script type=\"text/javascript\">
                        //Load player api asynchronously.
                        var tag = document.createElement('script');
                        tag.src = \"//www.youtube.com/player_api\";
                        var firstScriptTag = document.getElementsByTagName('script')[0];
                        firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

                        var player;
                        function onYouTubePlayerAPIReady() {
                            player = new YT.Player('youtubeVideoContainer', {
                              height        : \"".$height."\",
                              width         : \"".$width."\",
                              videoId       : \"".$id."\",
                              playerVars    : ".json_encode($this->playerParams)."
                            });
                        }
                    </script>

Please do not pay attention to \ ", it is displayed in PHP, so it is just for screening, also, the video plays, so no serious errors :)

Which annoys me, every time I request a video, I see this message in the console: An unsafe JavaScript attempt to access a frame with a URL
