# Fields show up as nested JSON in Kibana
When Packetbeat exports a field of type dictionary, and the keys are not known in advance, the Discovery page in Kibana will display the field as a nested JSON object:
```shell
http.response.headers = {
        "content-length": 12,
        "content-type": "application/json"
}
```

To fix this you need to [reload the index pattern](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2575/explore-analyze/find-and-organize/data-views) in Kibana under the Management→Index Patterns, and the index pattern will be updated with a field for each key available in the dictionary:
```shell
http.response.headers.content-length = 12
http.response.headers.content-type = "application/json"
```
