@Nullable
private static com.fasterxml.jackson.databind.JsonNode missingValueForType(java.lang.String name)
```
    Mapping between ES type and json value that represents missing value during aggregations. This value can't be null and should match type or the field (for ES long type it also has to be json integer, for date it has to match date format or be integer (millis epoch) etc.
    It is used for terms aggregations to represent SQL null.
    
    Parameters:
    
    name - name of the type (long, keyword ...)
    
    Returns:
    
    json that will be used in elastic search terms aggregation for missing value
