I've build an application server based on the OOTB image from Docker Hub (https://hub.docker.com/r/pegasystems/pega with tag '8.3'). The application server boots up without any problems and I can login. However, re-indexing the default search indexes fails. Or better yet, the won't even start re-indexing (no rule counter, no file size, etc). The Search Index Host Node is online with the default path '/search_index'. I've tried changing the indexpath by altering the DSS, but without luck.
Any ideas why the re-indexing isn't working? Hitting 'Cancel' and 'Re-index' won't help.
