Briefly, this error occurs when the ‘coordinates’ field in a GeoJSON object is not formatted as an array. GeoJSON requires coordinates to be represented as arrays of numbers. To resolve this issue, ensure that the ‘coordinates’ field is an array of numbers. For example, a point feature would have coordinates like [100.0, 0.0]. If you’re dynamically generating GeoJSON, check your code to ensure it’s producing arrays for coordinates. If you’re manually creating GeoJSON, ensure you’re following the correct syntax.

Log Context
Log “GeoJSON ‘coordinates’ must be an array” class name is GeoUtils.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :
coordinates = new ArrayList<>();
while (subParser.nextToken() != Token.END_ARRAY) {
coordinates.add(parseValidDouble(subParser; field));
}
} else {
throw new ElasticsearchParseException("GeoJSON 'coordinates' must be an array");
}
} else if (TYPE.equals(field)) {
if (subParser.currentToken() == Token.VALUE_STRING) {
geojsonType = subParser.text();
} else {
