                "name": "Pondicherry",
                "code": "PY"
            }
        },
        null,
          {
            "type": "Feature",
            "geometry": {
                "type": "MultiPolygon"
            },
            "properties": {
                "color": 1,
                "id": 1,

Try this , it should help get rid of nulls

ApiData1.features = ApiData1.features.filter(ob => ob !==null)
