I am getting this error when using geojson, looks like this should be supported by now, or do I need to change the crs? It looks like EPSG:4283 is not supported?
The latest Geojson spec dropped support for alternative CRSs RFC 7946: The GeoJSON Format. I would suggest switching to Lat/lon and height above WGS84 ellipsoid (EPSG:4979) to be spec compliant and trying again.
