Found the solution. An empty folder with the same name has to be created on local etc/app on every search heads. It solves the problem. Apps are working fine. For creating a new app on the search head pool: 1. create an app over the web page 2. it will throw an exception. 3. don't panic! 4. go to the search head's local etc/app folder(it will be on that search head where you the load balancer routed. So it is only on one search head) and move the appname folder to the shared etc/app/ folder 5. create the empty app folder in the local etc/app folder on every search heads. 6. now you can edit and use the new app 7. be happy! 😉 I hope that helps ...
