After enabling Now Assist virtual agent, a new search application is created automatically as the default one, with the default search profile and search sources.
So the existing search source for catalog item and KB has been changed, and the search sources associated search result action config is missing, which caused we can't open catalog item or KB in the search result.
The error for opening the KB article from search result is "record not found", the error for opening catalog item is that the view is form view instead of the expected catalog item view.
Why this happened? Why we have to manually add search result action config for the auto created search sources/applications to make it work as before enabling virtual agent? We don't want to create new search application/search sources for the employee center portal AI search.
