Hi!

I have a log file with json records like

```auto
{
  "request": {
    "foo": "bar"
  },
  "response": {
    "foo": "bar"
  }
}

```

and the following configuration for filebeat

```auto
- type: filestream
  paths:
    - /path/to/file
  tags: ["tags"]
  fields_under_root: true
  fields:
    field1: value1
  parsers:
    - ndjson:
        target: root
        overwrite_keys: true
        expand_keys: true

```

So I want to see the parsed fields like `root.request.foo` and `root.response.foo` but it doesn't works.

With `target: ""` it normally parse log records to `request.foo` and `response.foo`

Whats could be wrong?

Hi @ddoroshenko

did you try to add `add_error_key: true` [configuration](https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-input-filestream.html#_ndjson) and check if you can see any errors?  
do you actually have `root` field? what will happen if you change the target field to not yet existing one?

I'm very sorry  
It was simpy inattention. I had `target` at the wrong level
