Javascript error: cannot read properties of undefined (reading ‘trigger’)

  • Hi,
    Faced the following Javascript error:cannot read properties of undefined (reading ‘trigger’) in h5p.js?ver=1.15.4 line: 2810 while refreshing the page. The issue was not consistent. The issue appeared at times not during the initial load but while refreshing.

    As a temporary fix I had modified the Javascript file and wrapped the line 2810 with an if condition

     
if(window.parent.H5P.externalDispatcher){
    window.parent.H5P.externalDispatcher.trigger.call(this, event);
}

    Due to this error the H5P interactive video was not loading. The video content inside the iframe was empty.

    Most likely the theme or another plugin has altered the order of which the JavaScript files are loaded. Dependencies needs to be loaded first, i.e. the same order as a vanilla WordPress site with H5P uses.
