simply proceed with the example
make sure your geo mapping fields do not contain a dot
"source_location": { "ignore_malformed": true, "ignore_z_value": true, "type": "geo_point" }, "destination_location": { "ignore_malformed": true, "ignore_z_value": true, "type": "geo_point" },
–or– in case it’s too late, eventually consider a field rename or a field alias.
