list emr clusters using go

I'm trying to list emr clusters using go.

Here is the code I have that is returning blank. I did "the same" in python with correct results.

running := "RUNNING"

waiting := "WAITING"

emr_states := []*string {&running, &waiting}

var abc emr.ListClustersInput

abc.SetClusterStates(emr_states)

sess := session.Must(session.NewSession())

svc := emr.New(sess)

list_clusters_output, err := svc.ListClusters(&abc)

_ = err


println(fmt.Sprintf("type of list clusters output is %s", reflect.TypeOf(list_clusters_output)))

println(fmt.Sprintf("type of *list clusters output is %s", reflect.TypeOf(*list_clusters_output)))


list_clusters_output_dereffed := *list_clusters_output

println(list_clusters_output_dereffed.String())

The output I'm getting is

type of list clusters output is *emr.ListClustersOutput
type of *list clusters output is emr.ListClustersOutput
{
}

There is a cluster running that I have successfully returned with a python script.

Figured it out. I was missing region indication in the session.

Full solution below.

package main

import (
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/emr"	
)

func main() {

	starting := "STARTING"

	running := "RUNNING"

	waiting := "WAITING"

	emr_states := []*string {&starting, &running, &waiting}
	
	var abc emr.ListClustersInput
	
	abc.SetClusterStates(emr_states)

	sess := session.Must(session.NewSession())

	reggie := "us-east-1"

	sess.Config.Region = &reggie

	svc := emr.New(sess)

	list_clusters_output, err := svc.ListClusters(&abc)

	if err != nil {
		println(err.Error())
	}

	list_clusters_output_dereffed := *list_clusters_output

	println(list_clusters_output_dereffed.GoString())
	
}
