I'm using SAP Hybris version 2205, on the smartedit I'm getting 404 error for some smartedit extension's container.js and .js files that are whitelisted under smartedit configuration. I tried ant rushupdate from smartedittools extension path. I also have the required extensions as well which are mentioned in several other answers on community.
I found this similar link but this doesn't discuss about the generated .js files and I'm not sure if removing whitelisted url might result in removal of features(like personalization etc) from smartedit :
Any suggestions would be very helpful thanks in advance!
