Google compute engine googleapi:获取了HTTP响应代码404，未找到正文

当我试图使用Golang“libretto”的库从脚本实例VM时，我遇到了这个问题

vm := &gcp.VM{
    Name:        "test-vm-2",
    Zone:        "us-central1-f",
    MachineType: "n1-standard-1",
    SourceImage: "centos-7-v20181011",
    Disks: []gcp.Disk{
        {
            DiskType:   "pd-standard",
            DiskSizeGb: 10,
            AutoDelete: true,
        },
    },
    Preemptible:   false,
    Network:       "default",
    Subnetwork:    "default",
    UseInternalIP: false,
    Project:       os.Getenv(accountFile.ProjectID),
    Scopes: []string {
        "https://www.googleapis.com/auth/devstorage.read_write",
        "https://www.googleapis.com/auth/logging.write",
    },

    AccountFile: "key.json",
    SSHCreds: ssh.Credentials {
        SSHUser:       "VinCur",
        SSHPrivateKey: accountFile.PrivateKey,
    },
    SSHPublicKey: pub_ssh,
}

这是代码…一些解决方案
