aggregations json unmarshal error

[almondyoung]

cannot unmarshal array into Go struct field MetaAggregationResponse.aggregations.buckets of type map[string]interface {}

// MetaAggregationResponse struct for MetaAggregationResponse
type MetaAggregationResponse struct {
    // slice or map
    Buckets map[string]interface{} `json:"buckets,omitempty"`
    // support for auto_date_histogram_aggregation
    Interval *string `json:"interval,omitempty"`
    Value map[string]interface{} `json:"value,omitempty"`
}

buckets not support slice

func (c *APIClient) decode(v interface{}, b []byte, contentType string) (err error) {
//---
                } else if err = json.Unmarshal(b, v); err != nil { // simple model
            return err
        }
//---

Suggest use https://github.com/elastic/go-elasticsearch v7, this SDK is not good.
