Cannot write geojson collection- go

I’m able to add individual geojson data but not a collection package main

import (

"fmt"
"log"
_ "strings"

as "github.com/aerospike/aerospike-client-go"
shared "github.com/aerospike/aerospike-client-go/examples/shared"

) func main() { runRecord_Entry(shared.Client) runOptimal_Location(shared.Client)

log.Println("\t \t Application ran successfully GrandMaster")

} func runRecord_Entry(client *as.Client) {

// define a client to connect to

client, err := as.NewClient("127.0.0.1",3000)
PanicOnError(err)


//key, err := as.NewKey("test","testset","dert")
//key, _ := as.NewKey("test", "testset", "mapkey")


PanicOnError(err)
//binName := "gjsn"

// queries only work on indices
//client.DropIndex("writepolicy", "jolar", "jolardest", "set+binName")


// The Data
// The Data
points := []string{
	`{"type": "FeatureCollection",
		"features": [
			{
				"type": "Feature",

// define some bins
for i, ptsb := range points {
	key, _ := as.NewKey("test", "testset", i)
	bin := as.NewBin("vada", as.NewGeoJSONValue(ptsb))
	err := client.PutBins(shared.WritePolicy, key, bin)

	// write the bins
	//client.PutBins(shared.WritePolicy, key, bin)
	//client.PutBins(shared.WritePolicy, key, bin)

	//record, err := client.Get(shared.Policy, key, binName)
	shared.PanicOnError(err)
}
client.DropIndex(shared.WritePolicy, "test", "testset", "my_geo_inex_hu")
client.CreateIndex(shared.WritePolicy, "test", "testset","ma_geo_index","gjsn","as.GEO2DSPHERE")


fmt.Println("\t \t \t \t The records are wriiten !!")

}

func runOptimal_Location(client *as.Client){}

func PanicOnError(err error){ if err != nil{ panic(err) } }

The output , go run zarpin.go 2019/03/28 07:52:39 hosts: 127.0.0.1 2019/03/28 07:52:39 port: 3000 2019/03/28 07:52:39 namespace: test 2019/03/28 07:52:39 set: testset 2019/03/28 07:52:39 Invalid GeoJSON on insert/update

I’ve posted the same in a different section of the forum where the pointed the error may be in server. Thanks in advance !!
