onYouTubePlayerAPIReady doesn't get called after inject iframe via a chrome extension

I was playing around with the Youtube API and wanted to create a chrome extension that injects an iframe into the current website.



At first I'd try it out plainly and it works as intended:



(function() 
 // https://developers.google.com/youtube/iframe_api_reference
 console.log('loaded');

 const anchorPlay = document.createElement('a');
 anchorPlay.id = 'play-button';
 anchorPlay.innerHTML = 'Play';
 const anchorPause = document.createElement('a');
 anchorPause.id = 'pause-button';
 anchorPause.innerHTML = 'Pause';

 const iFrameElement = document.createElement('iframe');
 iFrameElement.setAttribute('id', 'video');
 iFrameElement.setAttribute(
 'src',
 'https://www.youtube.com/embed/krVkvyQjyBQ?enablejsapi=1&html5=1'
 );
 iFrameElement.setAttribute('allowfullscreen', '');
 iFrameElement.setAttribute('frameborder', '0');
 iFrameElement.setAttribute('height', '315');
 iFrameElement.setAttribute('width', '560');

 document.body.appendChild(anchorPlay);
 document.body.appendChild(anchorPause);
 document.body.appendChild(iFrameElement);

 // global variable for the player
 var player;

 // this function gets called when API is ready to use
 window.onYouTubePlayerAPIReady = function() 
 alert('called onYouTubePlayerAPIReady');
 // create the global player from the specific iframe (#video)
 player = new YT.Player('video', 
 events: 
 // call this function when player is ready to use
 onReady: onPlayerReady
 
 );
 ;

 function onPlayerReady(event) 
 // bind events
 var playButton = document.getElementById('play-button');
 playButton.addEventListener('click', function() 
 player.playVideo();
 );

 var pauseButton = document.getElementById('pause-button');
 pauseButton.addEventListener('click', function() 
 // player.pauseVideo();
 const currTime = player.getCurrentTime();
 alert(currTime);
 );
 

 // Inject YouTube API script
 var tag = document.createElement('script');
 tag.src = 'https://www.youtube.com/player_api';
 var firstScriptTag = document.getElementsByTagName('script')[0];
 firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
)();


https://codepen.io/thadeuszlay/pen/gQwwoZ



But once I create it as a chrome extension, the function window.onYouTubePlayerAPIReady doesn't get called. While all the elements get loaded correctly (buttons and iFrame are there and I can see my console logs).



The console is clean from errors. I can also see that the YT-API script got inserted correctly in the <head>. I deactivated my ad blocker, too.



In my Chrome extension, the content script looks exactly as the codepen code above. My manifest.json looks like this:




 "name": "test",
 "version": "1.0.0",
 "offline_enabled": true,
 "description": "test.",
 "permissions": ["activeTab", "tabs"],

    The API runs as a normal web page script, not in the isolated world of content scripts, so you need to put the code that accesses page variables such as window.onYouTubePlayerAPIReady into web page context, see Insert code into the page context using a content script
