I want to create a page not found report on AA. I try to detect the 404 page by using Launch. I found some old guides tell me to use s.pageType = "errorPage" (pageType )
Page not found question but it seems it is not working in Launch.
Please correct me if I am wrong.
The pageType:"errorPage" is working correctly however, pageName is also getting set.
Whatever, I find my own approach. I choose a prop to record the page URL when it is a 404 page.
