Pipeline output isolator pattern not working

[erikmathis]

I just converted a single pipeline to the mutli-pipeline as suggested here

When I stopped elasticsearch the file output stops working, the same problem as when it was a single pipeline. Am I missing something here?

Logstash Version 7.1.1

bash-4.2$ cat config/pipelines.yml
- pipeline.id: kube-audit-intake
  queue.type: persisted
  config.string: |
    input {       
      http {
        port => 8888
        enable_metric => false
        type => "kube-http-audit"
      } 
    }
    filter{
      if [type] == "kube-http-audit" {
        split {
          # Webhook audit backend sends several events together with EventList
          # split each event here.
          field=>[items]
          # We only need event subelement, remove others.
          remove_field=>[headers, metadata, apiVersion, kind, "@version", host]
        }
        mutate {
          rename => {items=>event}
          add_tag => [ "${ENVIRONMENT}" ]
        }
      }
    }
    output { pipeline { send_to => [file, es] } }
- pipeline.id: es
  queue.type: persisted
  config.string: |
    input { pipeline { address => es } }
    output {
      elasticsearch {
        hosts => ["http://elasticsearch.kube-audit.svc.cluster.local:9200"]
        index => "kubeaudit-%{+YYYY.MM.dd}"
        #user => "elastic"
        #password => "changeme"
        id => "elastic" 
      }
    }
- pipeline.id: file
  queue.type: persisted
  config.string: |
    input { pipeline { address => file } }
    output { 
      file {
        path => "/var/log/kube-audit/audit_%{+YYYY-MM-dd-HH}.log"
        create_if_deleted => true
        id => "file"
      }
    }
