storagegateway.ListGateways（）返回“无效资源”，状态码为：400

Question

I am having trouble using the go sdk to list all of the storage gateways in a region using the following code:

package main

import (
    "fmt"

    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/storagegateway"
)

func newSess() (sess *session.Session) {
    sess, err := session.NewSession(&aws.Config{
        Region: aws.String("us-east-2"),
    })

    if err != nil {
        fmt.Printf("Error creating session: %s
", err)
        return
    }

    return sess
}

func main() {
    sgw := storagegateway.New(newSess())

    input := &storagegateway.ListGatewaysInput{
        Limit:  aws.Int64(5),
        Marker: aws.String("1"),
    }

    result, err := sgw.ListGateways(input)
    if err != nil {
        fmt.Printf("Error listing gateways %s
", err)
        return
    }

    fmt.Println(result)

}

My environment is the following:

• Go version: 1.9.2 darwin/amd64
• Operating system: macOS 10.13.2
• aws-sdk-go: v1.12.63

The SDK is using the default profile specified in ~/.aws/config as it should and the credentials are correct as well. Furthermore, I am able to list the gateways using the awscli alone.

This could very well be something simple that I have overlooked as I am no expert. That said, any help would be greatly appreciated.
