Hi, I am following Logstash tutorial "Parsing Logs with Logstash". Ref: [https://www.elastic.co/guide/en/logstash/current/advanced-pipeline.html#\_configuring\_logstash\_for\_filebeat\_input](https://www.elastic.co/guide/en/logstash/current/advanced-pipeline.html#_configuring_logstash_for_filebeat_input) I am getting following error.
