Briefly, this error occurs when the LinearRing in a geo_shape query in OpenSearch doesn’t have the correct number of points. A LinearRing must have at least 4 points, where the first and last points are the same, forming a closed shape. To resolve this, ensure that your geo_shape query includes the correct number of points and that the first and last points are identical. Also, check for any syntax errors in your query.

Log Context
Log “invalid number of points in LinearRing (found [{}] – must be >= [{}])” class name is GeoShapeType.java. We extracted the following from OpenSearch source code for those seeking an in-depth context :
throw new OpenSearchParseException(error);
} int numValidPts = coerce ? 3 : 4;
if (coordinates.children.size() < numValidPts) {
throw new OpenSearchParseException("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)) {
