Filebeat not sending kubernetes metadata

[Martinho_MOREIRA]

Hi,

I just upgrade my filebeat from 7.10.2 to 7.11.2 and kubernetes metadata are missing now:
Here is my configuration file.
Did I miss something ?

filebeat.inputs:
- type: container
  paths:
    - /var/log/containers/*.log
  ignore_old: '15m'
  close_renamed: true
  fields:
    k8scluster: stagingeks
  tail_files: true
  json:
    keys_under_root: true
    ignore_decoding_error: true
    message_key: 'message'
  processors:
    - add_kubernetes_metadata:
        in_cluster: true
        host: ${NODE_NAME}
        matchers:
        - logs_path:
            logs_path: "/var/log/containers/"

Thanks,
Martinho
