Impossible to create Resources form Cloudformation resource Summaries

[Pymatteo]

There is a bug in the implementation of the cloud formation StackResourceSummary class which prevents the creation of StackResources by calling the Resource() sub-resource:

stack = cloudformation.Stack('MyStack') resource_summary = list(stack.resource_summaries.all())[0] resource_summary.dict {'meta': ResourceMeta('cloudformation', identifiers=['stack_name', 'logical_id']), '_logical_id': 'Aurora', '_stack_name': 'MyStack'} resource = list(stack.resource_summaries.all())[0].Resource() resource.dict {'meta': ResourceMeta('cloudformation', identifiers=['stack_name', 'logical_id']), '_stack_name': 'MyStack', '_logical_id': 'Aurora'}

stack_name and logical_id have been switched

resource.load() Traceback (most recent call last): File "", line 1, in File "/home/matteo/.local/lib/python3.6/site-packages/boto3/resources/factory.py", line 505, in do_action response = action(self, *args, **kwargs) File "/home/matteo/.local/lib/python3.6/site-packages/boto3/resources/action.py", line 83, in call response = getattr(parent.meta.client, operation_name)(**params) File "/home/matteo/.local/lib/python3.6/site-packages/botocore/client.py", line 272, in _api_call return self._make_api_call(operation_name, kwargs) File "/home/matteo/.local/lib/python3.6/site-packages/botocore/client.py", line 576, in _make_api_call raise error_class(parsed_response, operation_name) botocore.exceptions.ClientError: An error occurred (ValidationError) when calling the DescribeStackResource operation: Stack 'Aurora' does not exist

Reopening on behalf of @dhx-mike-palandra, reported this is still an issue in #2828. I will check in with the CloudFormation team on this. Thanks!

Thank you very much @kdaily. I just submitted another closely related issue: #2855. Since that issue involves the same model definition, and is even more essential for a properly functioning class at runtime, please consider checking in with the CloudFormation team about that one too.
