We reinstalled Kibana and Elastic with 7.12 and are accustomed to look at certain documents through just pure json, since it has a specific order and grouping. After the upgrade, the JSON tab seems to "pretty print" the json or such, flattening the object to one level making it impossible to get a good visual on the data point. It also seems to put each data point in an array.
When inspecting the API request made by Kibana, I noticed that _source is set to false.
"_source": false, and _source is never returned with the response. When I ran the exact same request through curl but change _source to true, it does indeed return _source as well.
Is there any way to change so that either _source is available through the JSON tab under Discovery, or so that the data in general can be shown closer to the original source?
