Briefly, this error occurs when the number of points provided to form a LinearRing in a GeoShape query in Elasticsearch is less than the required minimum. A LinearRing must have at least 4 points, including the start and end points which must be the same. To resolve this, ensure that you provide at least 4 points in your GeoShape query and that the first and last points are identical.
This guide will help you check for common problems that cause the log ” invalid number of points in LinearRing (found [{}] – must be >= [{}]) ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: .
Log Context
Log “invalid number of points in LinearRing (found [{}] – must be >= [{}])” class name is GeoShapeType.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
throw new ElasticsearchParseException(error);
} int numValidPts = coerce ? 3 : 4;
if (coordinates.children.size() < numValidPts) {
throw new ElasticsearchParseException("invalid number of points in LinearRing (found [{}] - must be >= [{}])";
coordinates.children.size(); numValidPts);
}
// close linear ring iff coerce is set and ring is open; otherwise throw parse exception
if (coordinates.children.get(0).coordinate.equals(
coordinates.children.get(coordinates.children.size() - 1).coordinate) == false) {
