我应该在vpc.addGatewayEndpoint（）的服务ID中输入什么？

Question

引发错误：

The Vpc Endpoint Service 'igw-id-123' does not exist (Service: AmazonEC2; Status Code: 400; Error Code: InvalidServiceName; Request ID: [UUID]; Proxy: null)

vpc.addGatewayEndpoint('igw-id-123', {
    service: { name: NETWORKING.PRIVATE_SUBNET_ID },
    subnets: [{ subnets: [NETWORKING.PUBLIC_SUBNET_2B] }]
});

文档没用
