Briefly, this error occurs when Elasticsearch expects a list of points (coordinates) for a geospatial query, but only receives a single point. This could be due to incorrect formatting or data input. To resolve this issue, ensure that your data input matches the expected format. If you’re using a geo_shape query, make sure you’re providing an array of points. If you’re using a geo_point query, ensure you’re providing a single point. Also, check your mapping to ensure it matches the data type you’re querying.

}
List points = new ArrayList<>();
for (CoordinateNode node : children) {
points.add(node.asPoint());
}
