I have the following simple `when.not` I am using for testing:

```auto
    processors:
      - decode_json_fields:
          when.not:
            or:
              - equals.input.type: "docker"
          fields: ["log"]
          target: "log_json"
          process_array: true
          max_depth: 20

```

Although, I am still seeing events that have and input.type equal to "docker" being processed. Is this syntax correct? I am using an `or` here as a test as I will have more than one not condition once I get this simple one working.

Thanks!
