=== Fields show up as nested JSON in {kib}

When {beatname_uc} exports a field of type dictionary, and the keys are not known in advance, the Discovery page in {kib} will display the field as a nested JSON object:

[source,shell]
----------------------------------------------------------------------
http.response.headers = {
        "content-length": 12,
        "content-type": "application/json"
}
----------------------------------------------------------------------

To fix this you need to {kibana-ref}/index-patterns.html#reload-fields[reload the index pattern] in {kib} under the Management->Index Patterns, and the index pattern will be
updated with a field for each key available in the dictionary:

[source,shell]
----------------------------------------------------------------------
http.response.headers.content-length = 12
http.response.headers.content-type = "application/json"
----------------------------------------------------------------------
