Hello,  
I am trying to produce a bar chart in Kibana using Vega.  
I use Vega because I have to use nested fields, and it seems there are not other options.  
This is my script:

```auto
{
  "$schema": "https://vega.github.io/schema/vega-lite/v5.json",
  "title": "Event counts from all indexes",
  data: {
    url: {
      %context%: true
      %timefield%: timestamp
      index: search-sonarqube-telemetry-2021-merged
      body: {
        "aggs": {
          "languages": {
            "terms": { "field": "plugins.name.keyword"}  
          }
        }
        size: 0
      }
    }
    format: {property: "aggregations.languages.buckets" }
  }
  
 
  mark: bar

  encoding: {
    x: {
      field: buckets.key
      type: nominal
      axis: { title: null }
    }
    y: {
      field: buckets.doc_count
      type: quantitative
      axis: { title: "Document count" }
    }
    
  }
    
}

```

I get the warnings:

- Infinite extent for field "buckets.doc\_count\_start": [Infinity, -Infinity]

- Infinite extent for field "buckets.doc\_count\_end": [Infinity, -Infinity]

and everything is empty.

If I try to debug, I see the source\_0 but not the data\_0.

What is wrong in my script?  
Thanks

I found the problem.  
I defined the property as aggregations.languages.buckets, but the I was defined the fields as buckets.key and buckets.doc\_count in the encoding.  
It was enough to replace key and doc\_count to buckets.key and buckets.doc\_count and it worked.  
Actually it was not finding the fields because inside aggregations.languages.buckets we don't have a repetition of buckets.

Could you post your final code? I don't understand the fix you described. Thanks!
