I've tried several times to load a geojson file into a index through Kibana import system. It gives me the preview of the polygons, creates a index, but the it returns me an error
"Error performing fetch: Request Entity Too Large"
with a doc_count of 0.
I've tried also with a single polygon and the problem was the same. So I guess it a geojson formatting issue. Could you help me with some kind of valid template that I can use?
