Entire html is wrapped by div tag on "viewsourcepage"
Hi,
I have 404 page in AEM 6.2 and if I change 404 to some random errors.html it is redirecting to 404 page. I have observed that the html is wrapped by <div> tag on viewsourcepage. Any solution to get rid off div tag ?? I have tried with cq:noDecoration: {boolean} true also unfortunately have noticed side effects on component level. So looking for any other solution.
Below is the sample viewsourcepage code:
