When uploading a geojson file into a map, Kibana hangs indefinitely on "Writing to index".
It's the same issue as in this fixed bug: https://github.com/elastic/kibana/issues/40102
I have Kibana v7.6.1, so it should be fixed in this version.
The index I want to use is one of these (I think this is the website I got it from): https://datamillnorth.org/dataset/ons-ward-boundaries
The geojson file is only 1.7 MB. I've had the same problem with all the other geojson files I've tried. I haven't successfully uploaded any geojson files.
If I look in Index Management, the index is present, but it doesn't come up as an option when I make a new map and try to add an index layer.
