Briefly, this error occurs when Elasticsearch expects a geographical point data type but receives an incorrect format. This usually happens when indexing documents with geo_point fields. The geo_point type requires a specific format: “lat, lon” or an object with “lat” and “lon” properties. To resolve this, ensure that the data being indexed matches the expected format. If the data is coming from an external source, you may need to preprocess it to match the required format. Also, check your mapping to ensure the field is correctly set as geo_point.

Log Context
Log “point expected” class name is CartesianPoint.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
return point.reset(x; y);
} else if (parser.currentToken() == XContentParser.Token.VALUE_STRING) {
String val = parser.text();
return point.resetFromString(val; ignoreZvalue);
} else {
throw new ElasticsearchParseException("point expected");
}
} public static CartesianPoint parsePoint(Object value; boolean ignoreZValue) throws ElasticsearchParseException {
return parsePoint(value; new CartesianPoint(); ignoreZValue);
