i am trying to save list of maps contents to Elasticsearch(as nested type)and it is failing. sample code is below  
package main

import (  
"fmt"  
)

const RegisterIndex = "register"  
const KpiIndex = "kpi"

// Register & Kpi Index doc type  
const RegisterDocType = "register"  
const KpiDocType = "kpi"

const KpiMapping = ` { "mappings": { "kpi": { "properties": { "kpi": { "type": "nested" } } } } }`

func main() {  
fmt.Println("Hello, playground")  
var List\_CounterData interface{}  
List\_CounterData = map[string]interface{}{}  
err := saveKpi(List\_Counterdata)  
if err != nil {  
fmt.Println("error in save")  
}   
}

func saveKpi(kpi interface{}) error {  
put1, err := elasticSearchClient.Index().  
Index(KpiIndex).  
Type(KpiDocType).  
Id("1001").  
BodyJson(kpi).  
Do(elasticSearchContext)  
if err != nil {  
fmt.Println("Failed to store Kpi , %v", err.Error())  
return err  
}  
fmt.Println("Indexed %s to index %s, type %s\n", put1.Id, put1.Index, put1.Type)  
return err  
}

My List\_Counterdata sample is below

> List\_Counterdata = [map[name: kisha] map[name: kish age: 29]]

When trying to create index, following the error

> elastic: Error 400 (Bad Request): failed to parse [type=mapper\_parsing\_exception]
