Currently, if an assessed app server listener cannot be found, the CCMA will simply vanish with the app without any visual indication of what happened. This creates great confusion for the customer who believes they are migrating all the apps they assessed.

The only indication is a warning in the Server/DC logs:

WARN [pool-xxxx-thread-x] [agent.service.catalogue.PlatformService] forEach my.App.Key has an automated path but missing a server listener. This app will be ignored during app migration.
