Problem when creating the DB Cluster with the subnet group. This is the error gotten: cdkWorkDocCluster DB subnet group 'CdkWorkSubnetGroup' does not exist. (Service: AmazonRDS; Status Code: 404; Error Code: DBSubnetGroupNotFoundFault; Request ID: 97c57053-46ad-4b10-ae26-879b01821f45). This occurs when using camelcase for the name of the subnet. When hyphens are introduced, it works okay.
