How to check if a custom VPC already exist using AWS CDK?

I am doing a CDK script and to use the default VPC, I has this code:

vpc = ec2.Vpc.fromLookup(this, "UseDefaultVPC", {
  isDefault: true
});

To use a existing VPC (not default), I has this code (will search by existing tags):

vpc = ec2.Vpc.fromLookup(this, "UseCustomVPCAlreadyCreated", {
  tags: {
    environment: project.environment,
    project_name: project.name
  }
});

I need on the first time, that VPC be created, and on a update be reused. Something like this:

Try to use a existing vpc, if does not exist, create it

try {
  vpc = ec2.Vpc.fromLookup(this, "UseCustomVPCAlreadyCreated", {
    tags: {
      environment: project.environment,
      project_name: project.name,
    },
  });
  console.log("Using a custom VPC: ", vpc.vpcId);
} catch (error) {
  vpc = new ec2.Vpc(this, "CreateNewVPC", {
    cidr: "10.0.0.0/16",
    maxAzs: 99, // 99 to use all AZs
  });
  console.log("VPC does not exist, creating it: ", vpc.vpcId);
}

But my try catch does not work. And the output is:

It try two times and fail, don't go to catch:

$ cdk deploy --profile fagianijunior
