SubnetSelection "OnePerAZ" adds more than one per AZ

[githubnoobieme]

Hello,

when I try to use SubnetSelection and the option "OnePerAZ" it just creates a template of all subnets that are attached to the vpc and not only 1 per AZ

This is the code Iam using

vpc1.add_interface_endpoint('SSMEndpoint', service=ec2.InterfaceVpcEndpointAwsService('ssm'), subnets=ec2.SubnetSelection(subnet_type=ec2.SubnetType.PRIVATE, one_per_az=True))

And this is my output

VPC2SSMEndpoint635B3888:
Type: AWS::EC2::VPCEndpoint
Properties:
ServiceName:
Fn::Join:
- ""
- - com.amazonaws.
- Ref: AWS::Region
- .ssm
VpcId: vpc-0756804582992c518
PrivateDnsEnabled: true
SecurityGroupIds:
- Fn::GetAtt:
- VPC2SSMEndpointSecurityGroupC16A4318
- GroupId
SubnetIds:
- subnet-02763f47226fccxxx
- subnet-0c2af8bb871b359x
- subnet-0099cf88bcb36222
- subnet-0000db6c52c8ddc22
- subnet-0fb87224a65d3842
- subnet-0ed2bf836eb579c22
VpcEndpointType: Interface

Not sure if Iam doing something wrong or this option is not working properly
