We are currently testing the upgrade from 23.2 to 24.2.3. One IG returns this JS error and doesn't display anything:

DOMPurify cannot be found

It's coming from util.js:

    sanitizeHtml: html => {
       if ( window.DOMPurify ) {
           return window.DOMPurify.sanitize( html, {
               // extend the existing array of allowed attributes
               ADD_ATTR: [ "target" ]
           } );
       } else {
           throw new Error( "DOMPurify cannot be found." );
       }
   }

I really have no idea what this means and why this is suddenly a problem for one IG (found so far anyway).

Does anyone have any idea? (This forum is usually faster than Oracle Support :-))
