github.com/aws/aws-sdk-go Go library panics on svc.ReceiveMessage: panic: runtime error: index out of range

Hi,

My code receives messages from an AWS SQS queue but not locally with goaws. Is this a bug?


sess, _ := session.NewSession(&aws.Config{
    Region: aws.String("eu-west-2"),
    Endpoint: aws.String("http://localhost:4100"),
},
)

svc := sqs.New(sess)

result, err := svc.ReceiveMessage(&sqs.ReceiveMessageInput{
    AttributeNames: []*string{
        aws.String(sqs.MessageSystemAttributeNameSentTimestamp),
    },
    MessageAttributeNames: []*string{
        aws.String(sqs.QueueAttributeNameAll),
    },
    QueueUrl:            &queueUrl,
    MaxNumberOfMessages: aws.Int64(1),
    VisibilityTimeout:   aws.Int64(20), // 20 seconds
    WaitTimeSeconds:     aws.Int64(0),
})

But something is causing it to panic on svc.ReceiveMessage

go run *.go
panic: runtime error: index out of range

I can get a message with the cli tool
