so I have the following setup: NETWORK project, which creates a simple awsx.vpc

// Allocate a new VPC that uses all of the current region's availability zones:
const vpc = new awsx.ec2.Vpc(`lsports-${getStack()}`, {
  numberOfAvailabilityZones: "all",
  subnets: [
    { type: "public" },
    { type: "private" },
    { type: "isolated", name: "db" },
    { type: "isolated", name: "redis" },
  ],
  tags: baseTags,
});

and the following ECS project

const vpc = awsx.ec2.Vpc.fromExistingIds(`lsports-${getStack()}`, {
  vpcId: network.getOutput("vpcId"),
});

// Create a load balancer on port 80 and spin up two instances of Nginx.
const alb = new awsx.elasticloadbalancingv2.ApplicationLoadBalancer(
  "web-traffic",
  {
    vpc: vpc,
    subnets: network.getOutput("publicSubnetIds"),
    tags: baseTags,
  }
);

const listener = alb.createListener("web-listener", { port: 80 });

const nginx = new awsx.ecs.FargateService("nginx", {
  tags: baseTags,
  taskDefinitionArgs: {
    containers: {
      nginx: {
        image: "nginx",
        memory: 128,
        portMappings: [listener],
      },
    },
  },
  desiredCount: 2,
});

I'm getting the following error:

* error creating application Load Balancer: ValidationError: At least two subnets in two different Availability Zones must be specified
        status code: 400, request id: 99ff6eef-e935-43e3-b34a-cf36251db0e7

which is weird, since I have public subnets across all AZ's, if I create the VPC in the same project everything seem to work as expected
