Hi there,

I have the below defined in my output.kafka section

```auto
    topics:
      - topic: "my-topic"
        when:
          and:
              - equals:
                kubernetes.namespace: "test"
              - has_fields: ["someField"]

```

I get an error with my config  
`Exiting: error initializing publisher: missing or invalid condition`

I then tested just the "has\_fields" condition, i.e.

```auto
    topics:
      - topic: "my-topic"
        when:
              has_fields: ["someField"]

```

And this works perfectly. Does has\_fields not work in conjunction with "and"? If it does, what am I doing wrong?

Thanks
