cloudformation

While working on CloudFormation template, and storing the output of the endpoint attribute of a memcached backed cache cluster resource, I used the Fn::GetAtt (!GetAtt) function and came across this message

An error occurred (ValidationError) when calling the CreateStack operation: Template error: resource CacheClusterFoo does not support attribute type ConfigurationEndPoint.Address in Fn::GetAtt

1	An error occurred (ValidationError) when calling the CreateStack operation: Template error: resource CacheClusterFoo does not support attribute type ConfigurationEndPoint.Address in Fn::GetAtt

Example

Outputs:
  OutputCacheClusterEndpointFoo:
    Value: !GetAtt [ CacheClusterFoo,ConfigurationEndpoint.Address ]
    Export:
      Name: !Join [ ":", [ !Ref ParamVpcStackName, CacheClusterEndpointFoo ] ]

Outputs:

OutputCacheClusterEndpointFoo:

Value: !GetAtt [ CacheClusterFoo,ConfigurationEndpoint.Address ]

Export:

Name: !Join [ ":", [ !Ref ParamVpcStackName, CacheClusterEndpointFoo ] ]

It took me some time to realise where I had gone wrong! ConsiderConfigurationEndPoint.Address vs ConfigurationEndpoint.Address. p vs. P!

Thanks to Stack Overflow for pointing this out
