video.es.js:228 VIDEOJS: ERROR: TypeError: Cannot read properties of undefined (reading 'enabled')

Hello, I am trying to use this plugin but I am facing some issues. I am using the plugin in an Angular app/ Ionic app. The videojs version that I have installed in the project is "^7.20.3" and the plugin version is "^1.0.16".

I am initializing the library like this:

  ngOnInit() {
    this.player = videojs(this.target.nativeElement, this.options, function onPlayerReady() { });
    this.player.ads({
      debug: true
    });

    this.player.vast(
      {
        seekEnabled: true,
        controlsEnabled: true,
        wrapperLimit: 10,
        withCredentials: false,
        skip: 8,
        url: 'https://example'      
      }
    );
    this.player.src('example.mp4', 'application/x-mpegURL')
  }

But I am getting this error:

video.es.js:228 VIDEOJS: ERROR: TypeError: Cannot read properties of undefined (reading 'enabled')

Any ideas why I am getting this error?
Thanks in advance!
