Briefly, this error occurs when the coordinates provided for a geo_shape in Elasticsearch are not forming a closed loop, which is a requirement for LinearRing. To resolve this issue, ensure that the first and last points of your coordinates are the same, thus forming a closed shape. Also, check that your coordinates have at least four points, as a valid LinearRing must have at least four coordinates.
This guide will help you check for common problems that cause the log ” invalid LinearRing found (coordinates are not closed) ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: .
Log Context
Log “invalid LinearRing found (coordinates are not closed)” class name is GeoShapeType.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
coordinates.children.get(coordinates.children.size() - 1).coordinate
) == false) {
if (coerce) {
coordinates.children.add(coordinates.children.get(0));
} else {
throw new ElasticsearchParseException("invalid LinearRing found (coordinates are not closed)");
}
}
} @Override
