I was looking at this guide:
And used the following official code from the page above to create an example doc with the example index:
PUT my_index/_doc/1 { "text": "Geo-point as an object", "location": { "lat": 41.12, "lon": -71.34 } }
When I attempt to view a visualization it says that I have no geohash fields but according to the record that I created this should work since geopoints can be objects.
I use 6.5.1 version for ELK.
