Hi,  
I am trying to define service as the content of [app.kubernetes.io/name](http://app.kubernetes.io/name) label if it empty by:

```auto
    if ![service] and [kubernetes][labels][app_kubernetes_io/name] {
        mutate {
            add_field => { "service" => '[kubernetes][labels][app_kubernetes_io/name]'}
        }
    } 

```

And a lot of variants of it (e.g. "%{[kubernetes][labels][app\_kubernetes\_io/name]"}) but failed (with above, I got the text instead the value).  
I am using Logstash 7.16.3.  
Thanks
