CloudControlApi GetResource fails with validation error at 'dBProxyName'

[greg5123334]

When trying to get details for a AWS::RDS::DBProxyTargetGroup via the Cloud Control API, the request fails with a validation error.

Reproduction

Deploy AWS::RDS::DBProxyTargetGroup

cluster = rds.DatabaseCluster(self, "Database",
                                cluster_identifier=cluster_identifier,
                                engine=rds.DatabaseClusterEngine.aurora_postgres(
                                    version=rds.AuroraPostgresEngineVersion.VER_15_2),
                                credentials=rds.Credentials.from_generated_secret(
                                    "syscdk"),
                                instance_props=rds.InstanceProps(
                                    instance_type=instance_type,
                                    vpc_subnets=ec2.SubnetSelection(
                                        subnet_type=ec2.SubnetType.PUBLIC),
                                    vpc=vpc
                                ),
                                storage_type=rds.DBClusterStorageType.AURORA_IOPT1,
                                removal_policy=removal_policy,
                                )

proxy = rds.DatabaseProxy(self, "Proxy",
    proxy_target=rds.ProxyTarget.from_cluster(cluster),
    secrets=[cluster.secret],
    vpc=vpc
)
