Invalid number of lines in MultiLineString found – must be >= 1 – How to solve this Elasticsearch exception

Briefly, this error occurs when Elasticsearch tries to process a MultiLineString in a geo_shape field, but the number of lines provided is less than 1. This is invalid as a MultiLineString must contain at least one line. To resolve this issue, ensure that the MultiLineString you’re trying to index contains at least one line. If the field is optional, consider using a null value or omitting the field entirely when no lines are available. Alternatively, check your data source or ingestion process to prevent empty MultiLineStrings from being created.

Log Context

Log “invalid number of lines in MultiLineString (found [{}] – must be >= 1)” class name is GeoShapeType.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 }  @Override
 CoordinateNode validate(CoordinateNode coordinates; boolean coerce) {
 if (coordinates.children.size() < 1) {
 throw new ElasticsearchParseException("invalid number of lines in MultiLineString (found [{}] - must be >= 1)";
 coordinates.children.size());
 }
 return coordinates;
 }
 };
