Requested attribute Address does not exist in schema for AWS::MemoryDB::Cluster

Question

I created a MemoryDB for Redis with cloudformation and I wanted to output the cluster endpoint, this is the code:

```
memoryDBCluster:
    Type: AWS::MemoryDB::Cluster
    DependsOn:
      - Lambda1
      - Lambda2
    Properties:
      ClusterName: !Sub 'cluster-${Environment}'
      Description: Redis cluster
      EngineVersion: "7.0"
      ACLName: open-access
      NodeType: !Ref NodeType
      NumReplicasPerShard: 1
      NumShards: 1
      SecurityGroupIds:
        - !Ref memoryDBClusterSG
      SubnetGroupName: !Ref memoryDBClusterSubnetGroup
      TLSEnabled: true
```

I tried to output the endpoint in two ways:

first with
```
Outputs:
  ClusterAddress:
    Description: "The cluster Address"
    Value: !GetAtt memoryDBCluster.Address
```
With this I got "Requested attribute **Address** does not exist in schema for AWS::MemoryDB::Cluster"

and:

```
Outputs:
  ClusterAddress:
    Description: "The cluster Address"
    Value: !GetAtt memoryDBCluster.Endpoint.Address
```
in this case the error was "Requested attribute **Endpoint.Address** does not exist in schema for AWS::MemoryDB::Cluster"

is this a bug? where can I report it?

Answer

Hello,

From your query, I understand that you are trying to create a MemoryDB cluster for Redis with CloudFormation and want to output the cluster endpoint but you are facing error’s.

In order to fix the issue, please try to use : **"!GetAtt memoryDBClusterRedis.ClusterEndpoint.Address"** in the Outputs value.

See the below snippet:
```
Outputs:
  ClusterAddress:
    Description: "The cluster Address"
    Value: !GetAtt memoryDBClusterRedis.ClusterEndpoint.Address
```

The above approach should be fixing the error and you should be able to create the Cluster and output cluster’s address.

Thank you for bringing this issue to our attention. We're always looking forward to make our services easier to use for our customers, therefore I’ll be submitting the feedback internally to modify the AWS Documentation accordingly.

If you face any further errors or issues, then I would suggest you to open a support case with AWS for further troubleshooting. You can use the following link for the same: https://support.console.aws.amazon.com/support/home#/case/create
