Hello,

I have a logstash config that goes something like:

```auto
input{
  pipeline {
    address => "output1"
    codec => cef{
      ecs_compatibility => disabled
    }
  }
}

output {
  stdout {codec => rubydebug}
  
}

```

The input in this config is from a json output from another config file which has the CEF string in the "message" key.

However the CEF codec for this config is not working...
