Hi all,

I'm trying to remove some field on Fluentd by using plugin record\_transformer but it does not works.

I'm trying to delete 2 fields: "\_id" & "\_index". Below is my configuration file:

```auto
apiVersion: logging.banzaicloud.io/v1beta1
kind: ClusterFlow
metadata:
  name: cluster-flows
spec:
  filters:
  - dedot:
      de_dot_nested: true
      de_dot_separator: '-'
  - record_transformer:
      remove_keys: $["_index"],$["_id"]
  globalOutputRefs:
  - cluster-outputs

```

The log was pushed to Elasticsearch but I still see 2 above fileds as below:

```auto
{
  "_index": “bi-2022-09-29",
  "_id": "hhXBiIMBuHSGkxNA",
  "_version": 1,
  "_score": 0,
}

```

Please help me to fix the issue.  
Thanks,

---

This seems to be related to fluentd configuration, which is not supported here. I would recommend you reach out to the fluentd. community about this.
