Has anyone been able to use "enters viewport" or "element exists" Event Type in DTM with a Single Page Application? I would like to track when an error occurs. When an error occurs, an error element is added to the view with an element ID. I would like to track when that element (ID) is added to the DOM in order to track how many errors occur in a user session. In my implementation, when the error element shows on screen, nothing happens in Adobe Analytics debugger. Has anyone been able to successfully accomplish this? I can't find anything on this subject.
Using a dataLayer is out of the question because we don't have access to the code base.
