Hi guys, I have installed a new ELK stack platform on the same machine and also enabled the security features (user, roles). The problem I am facing is that Logstash starts and then crashes with the following logs: ``` [2019-07-11T11:51:23,075][INFO][logstash.runner] Starting Logstash {"logstash.version"=>"7.2.0"} [2019-07-11T11:51:29,266][INFO][logstash.outputs.elasticsearch] Elasticsearch pool URLs updated {:changes=>{:removed=>[], :added=>[http://logstash_internal:xxxxxx@127.0.0.1:9200/]}} [2019-07-11T11:51:29,549][WARN][logstash.outputs.elasticsearch] Restored connection to ES instance {:url=>"http://logstash_internal:xxxxxx@127.0.0.1:9200/"} [2019-07-11T11:51:29,667][INFO][logstash.outputs.elasticsearch] ES Output version determined {:es_version=>7} [2019-07-11T11:51:29,673][WARN][logstash.outputs.elasticsearch] Detected a 6.x and above cluster: the `type` event field won't be used to determine the document _type {:es_version=>7} [2019-07-11T11:51:29,735][INFO][logstash.outputs.elasticsearch] New Elasticsearch output {:class=>"LogStash::Outputs::ElasticSearch", :hosts=>["//127.0.0.1:9200"]} [2019-07-11T11:51:29,808][INFO][logstash.outputs.elasticsearch] Using default mapping template [2019-07-11T11:51:29,923][INFO][logstash.outputs.elasticsearch] Attempting to install template {:manage_template=>{"index_patterns"=>"logstash-*", "version"=>60001, "settings"=>{"index.refresh_interval"=>"5s", "number_of_shards"=>1, "index.lifecycle.name"=>"logstash-policy", "index.lifecycle.rollover_alias"=>"logstash"}, "mappings"=>{"dynamic_templates"=>[{"message_field"=>{"path_match"=>"message", "match_mapping_type"=>"string", "mapping"=>{"type"=>"text", "norms"=>false}}}, {"string_fields"=>{"match"=>"*", "match_mapping_type"=>"string", "mapping"=>{"type"=>"text", "norms"=>false, "fields"=>{"keyword"=>{"type"=>"keyword", "ignore_above"=>256}}}}}], "properties"=>{"@timestamp"=>{"type"=>"date"}, "@version"=>{"type"=>"keyword"}, "geoip"=>{"dynamic"=>true, "properties"=>{"ip"=>{"type"=>"ip"}, "location"=>{"type"=>"geo_point"}, "latitude"=>{"type"=>"half_float"}, "longitude"=>{"type"=>"half_float"}}}}}}} [2019-07-11T11:51:29,973][WARN][org.logstash.instrument.metrics.gauge.LazyDelegatingGauge] A gauge metric of an unknown type (org.jruby.specialized.RubyArrayOneObject) has been create for key: cluster_uuids.
