'semantic-search-v2.aws.magna.china.' 遇到 DomainLabelEmpty（域标签为空）

Question

我可以在 Route53 中创建 A 记录：

但是当我使用cdk代码做同样的事情时。它失败了。 这是代码：

    // ALB names are limited to 32 characters...workaround
    let lbNameLength = 28 
    let truncatedServiceName = props.serviceName.substring(0, lbNameLength)

    // Creating an internet facing ALB
    const loadBalancer = new elbv2.ApplicationLoadBalancer(this, "alb", {
      vpc: props.cluster.vpc,
      vpcSubnets: {
        subnets: props.cluster.vpc.privateSubnets
      },
      loadBalancerName: `${truncatedServiceName}-lb`,
      idleTimeout: Duration.seconds(3600)
    });

    // Allowing incoming connections 
    loadBalancer.connections.allowFromAnyIpv4(ec2.Port.tcp(props.lbPort), "Allow inbound HTTP");

    // Creating a listener and listen to incoming requests
    const listener = loadBalancer.addListener("listener", {
      port: props.lbPort,
      protocol: elbv2.ApplicationProtocol.HTTP
    });

    // Creating a target group that points to the application container (e.g. port 8080)
    listener.addTargets("targets", {
      port: props.containerPort,
      protocol: elbv2.ApplicationProtocol.HTTP,
      targets: [service],
      healthCheck: {
        path: '/health'
      }
    });

    const dnsParams= dnsParameters(this, id)

    const magnaHostedZone = route53.HostedZone.fromHostedZoneAttributes(this, 'hostedZone', {
      hostedZoneId: dnsParams.hostedZoneId,
      zoneName: dnsParams.zoneName
    })

    // Using alias because load balancer is an AWS resource
    new route53.ARecord(this, 'aRecord', {
      zone: magnaHostedZone,
      target: route53.AddressRecordTarget.fromAlias(new targets.LoadBalancerTarget(loadBalancer)),
      recordName: "semantic-search-v2"
    });

当我运行这个typescript cdk代码时，出现了这个错误：

DomainLabelEmpty (Domain label is empty) encountered with 'semantic-search-v2.aws.magna.china.' (Service: AmazonRoute53; Status Code: 400; Error Code: InvalidInput; Request ID: 9f643150-262c-43fc-87ff-800dca172171; Proxy: null)

我不知道 'DomainLabelEmpty' 是什么意思。

顺便说一句，我帐户的所有子网都是私有的，无法访问 public 网络。

在此先感谢您对我的帮助！

尝试将 r53 托管区域名称附加到 ARecord 的 recordName 属性。
