Failed to execute postMessage on DOMWindow

[spyesx]

Hi !

The following error keeps showing up constantly for a few days.

• the website uses HTTPS
• there is no autoplay
• the origin is set manually just in case (ie: no window.location.origin)

www-widgetapi.js:629 Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://youtube.com') does not match the recipient window's origin ('https://www.DOMAIN.TLD').

Tested on Chrome, Firefox and Safari.

The code is as follow:

      this._player = new YTPlayer('#player', {
        width: '100%',
        height: '100%',
        caption: false,
        controls: false,
        keyboard: false,
        fullscreen: true,
        annotations: false,
        modestBranding: true,
        related: false,
        host: 'https://www.youtube.com',
        showInfo: false,
        origin: 'https://www.DOMAIN.TLD'
      })
      this._player.load(this._YTVideoID)

Did I miss something?

Answer to myself and those who will face it.

Autoplay will not work. Play right after a load will not work.

      this._player = new YTPlayer('#player', {
        width: '100%',
        height: '100%',
        autoplay: true,
        caption: false,
        controls: false,
        keyboard: false,
        fullscreen: true,
        annotations: false,
        modestBranding: true,
        related: false,
        mute: 1,
        host: 'https://www.youtube-nocookie.com',
        showInfo: false,
        origin: 'https://www.soniawiederatherton.com'
      })
      this._player.mute()
      this._player.load(this._YTVideoID)
      this._player.play()

However, if you mute the sound before playing the video, you'll be ok. I still don't know why we get a postMessage error though oO.

The previous solutions for autoplay did not work for me but I eventually found a solution that did.

Instead of turning on autoplay on YTPlayer, specify it on load.
player.load("video", [true])

Was there ever a solution to this, I keep getting these error messages over and over
