having index error while creating Vpc

[rsarili]

For this basic vpc definition below I got following error,

    const vpc = new ec2.Vpc(this, 'my-cdk-vpc', {
      cidr: '10.0.0.0/16',
    });

09:40:46 | CREATE_FAILED | AWS::EC2::Subnet | my-cdk-vpc/PublicSubnet2/Subnet
Template error: Fn::Select cannot select nonexistent value at index 1.
This is the part auto generated in cloudformation template

  mycdkvpcPublicSubnet2Subnet33F973F6:
    Type: AWS::EC2::Subnet
    Properties:
      VpcId:
        Ref: mycdkvpc037DA4AF
      AvailabilityZone:
        Fn::Select:
          - 1
          - Fn::GetAZs: ""

It seems error related to resources will be created by default. I just want to create a vpc without any explicit configuration(default ones are fine). Do you have any idea how can I achieve that? cdk version 2.50.0
