Briefly, this error occurs when the “coordinates” field in Elasticsearch receives less than two values. This is common when dealing with geospatial data, as coordinates typically require a pair of values (latitude and longitude). To resolve this issue, ensure that you’re providing at least two values for the “coordinates” field. If the data source doesn’t provide these, you may need to revise your data collection or processing methods. Also, check your mapping and indexing process to ensure that the correct number of values are being assigned to the “coordinates” field.
This guide will help you check for common problems that cause the log ” [coordinates] must contain at least two values ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: .
Log Context
Log “[coordinates] must contain at least two values” class name is GenericPointParser.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
if (coordinates != null) {
if (geojsonType == null || geojsonType.toLowerCase(Locale.ROOT).equals("point") == false) {
throw new ElasticsearchParseException("[type] for {} can only be 'Point'"; mapType);
}
if (coordinates.size() < 2) {
throw new ElasticsearchParseException("[coordinates] must contain at least two values");
}
if (coordinates.size() == 3) {
assertZValue(ignoreZValue; coordinates.get(2));
}
if (coordinates.size() > 3) {
