How to Reproduce

根据Aliyun 提供的 Go SDK Developer Guide 发现创建一直提示 user order resource type [classic][ecs.ic5.large] not exists in [eu-central-1] https://partners-intl.aliyun.com/help/doc-detail/66226.htm?spm=a2c63.p38356.b99.10.530013dcPeias5#:~:text=request%20%3A%3D%20ecs.CreateCreateInstanceRequest,exception%0A%20%20%20%20%20%20%20%20panic(err)%0A%20%20%20%20%7D

SecurityGroup 通过SDK已经创建好了

然后创建Instnace的代码如下一直报错提示not exists

panic: SDK.ServerError
ErrorCode: InvalidResourceType.NotSupported
Recommend: https://error-center.aliyun.com/status/search?Keyword=InvalidResourceType.NotSupported&source=PopGw
RequestId: 69B4559A-D344-
Message: user order resource type [classic][ecs.ic5.large] not exists in [eu-central-1]

request := ecs.CreateCreateInstanceRequest()
    request.ImageId = "alinux_17_01_64_20G_cloudinit_20171222.vhd"
    request.InstanceName = "MyInstance"
    request.SecurityGroupId = "sg-gwxxxxxxx"
    request.InstanceType = "ecs.ic5.large"
    request.ClientToken = utils.GetUUID()
    response, err := client.CreateInstance(request)

我也查看了 ECS Instance Types Available for Each Region 这个Instancetype 是可以使用的在Frankfurt https://ecs-buy.aliyun.com/instanceTypes/?spm=a2c63.p38356.879954.410.1eeb2d44NAboww#/instanceTypeByRegion

是有什么地方不对吗？
