body: <p>Filebeat stopped working after upgrading from 6.6.2 to 6.7.0</p>
  
  <p>My Filebeat configuration is:</p>
  
  <pre><code>filebeat.inputs:
  - type: log
    enabled: true
    paths:
      - /var/www/current/log/production.log
      - /var/www/current/log/api_v2.production.log
    multiline.pattern: '^[EIWDF]\, '
    multiline.negate: true
    multiline.match: after
  filebeat.config.modules:
    path: ${path.config}/modules.d/*.yml
    reload.enabled: false
  setup.template.settings:
    index.number_of_shards: 3
  setup.kibana:
  output.elasticsearch:
    hosts: ["ip:29200"]
  </code></pre>
  
  <p>But /var/log/filebeat/filebeat shows:</p>
