Wrapping a JSON string

[Steve Champagne]

Hello,

I'm ingesting some JSON data that I'd like to wrap in a json_string field
as a string type. I tried using a JsonPathReader with a dynamic property
'json_string' and a value of $, but I seem to be getting back a string
version of the JSON:

{"partition_date":"2018-01-01T00:00:00.000Z","json_string":"{@timestamp=2018-01-01T00:00:00.000Z,
id=1, name=John}"}

I was wondering if there was a way that I could do this and preserve the
raw JSON format?

Thanks,
Steve
