Failed to execute 'postMessage' on 'DOMWindow

[123ndy]

I get this message in console: Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://www.youtube.com') does not match the recipient window's origin ('https://mydomain.com').

I have read that a combo of http and https could be the reason, but in this case both the iframe and the hosted domain is using https.

Any idea of what it can be?

I'm actually not sure, as you might have noticed this error message does not appear very consistently (at least it doesn't for me) and it does not affect the YouTube player functionality. We depend on a chain of NPM modules to load the YouTube player for us so it is also not possible for us to fix this issue inside this module.

Yeah, it also sometimes happens when only using the official YouTube JS API. Try refreshing https://gateway.ipfs.io/ipfs/Qmb3ggu57cXHTh3JxCCF4cY3Sds21d4UdZZe6T3W5GfkHL/ a few times with an open console and you should see it pop up sometimes.

I was expecting this to sort it.. ? still have some sporadic errors.

 playerVars: { // https://developers.google.com/youtube/player_parameters
                       origin: 'https://mywebsite.com',
                       enablejsapi: '1',

did any one find a solution for this ?

Hmm i did find this just now: brandly/angular-youtube-embed#116

is it fixed if you add

window.YTConfig = {
  host: 'https://www.youtube.com' 
} 

somewhere in your app, before using react-youtube?

@goto-bus-stop Doesn't seem to work here.

I haven't find a solution for this issue, but I find a way to reproduce this issue.
If you have some tools like Charles, try to block the youtube iframe get call, you will see this error in your console every time.
I checked the Google's js file, they are just running iframe.contentWindow.postMessage, I am guessing that maybe when the iframe content loads slow, the postMessage call was sent to the main window? Not sure how contentWindow and postMessage really work.
