AWS::ElastiCache::GlobalReplicationGroup 的 Cloud Formation 模板

Question

wanted to create Redis global datastore using CF, following the guidelines https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-elasticache-globalreplicationgroup.html

but no luck, I can create Redis cluster but not the global data store: My code:

if any one can help, I am getting This error:

Properties validation failed for resource globalreplication with message: #/Members/0/Role: #: only 1 subschema matches out of 2 #/Members/0/Role: failed validation constraint for keyword [enum]

globalreplication:
Type: AWS::ElastiCache::GlobalReplicationGroup
DependsOn: RedisService
Properties:
  AutomaticFailoverEnabled: false
  GlobalReplicationGroupDescription: description example
  GlobalReplicationGroupIdSuffix: test
  Members:
    - ReplicationGroupId: !Ref ClusterName
      ReplicationGroupRegion: eu-west-1
      Role: PRIMARY

This will add the primary node and create new global data store and then need to add the secondary node in the newly created global data store, you can see the prefixes here https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Redis-Global-Datastores-CLI.html :

RedisService:
