Even though it can parse the name and the config_file, it cannot parse the install_directory. Custom configurations on the application side results in an inabilty to retrieve the install_directory The pattern steps look for keywords based on standard industry practices for the Kafka Broker server configuration. Since there are few Kafka Broker applications with custom configurations, being unable to retrieve the install_directory results in the IRE error. ResolutionTo resolve: Navigate to the following identifier entry, and check the allow null attribute.Post that, and then rerun Discovery. https://INSTANCE_NAME.service-now.com/nav_to.do?uri=%2Fcmdb_identifier_entry.do%3Fsys_id%3D5171205d1b97d05065d6a8ecbc4bcbcc%26sysparm_record_target%3Dcmdb_identifier_entry%26sysparm_record_row%3D1%26sysparm_record_rows%3D1%26sysparm_record_list%3Didentifier%253D9c612c1d1b97d05065d6a8ecbc4bcbec%255EORDERBYorder
