Loading YAML exercise is failing

Question

Following an exercise for "Containerized Applications on AWS". https://aws-tc-largeobjects.s3.us-west-2.amazonaws.com/DEV-AWS-MO-ContainersRedux/exercise-1-firstcontainer.html

For its first exercise it offered the following YAML: 
https://aws-tc-largeobjects.s3.us-west-2.amazonaws.com/DEV-AWS-MO-ContainersRedux/downloads/exercise-containers.yml.

While trying to load it I get the following error:
![Enter image description here](/media/postImages/original/IM4pt6qYdeQmK6qNBcRqCWtg)

It complains about:
The following resource types are not supported for resource import: AWS::EC2::VPCGatewayAttachment
I have not touched the YAML provided, therefore how can it fail?

There are no information with regard to, DeletionPolicy:
Resources to import must have a DeletionPolicy attribute specified in the template

Where can I find the proper YAML for the exercise?

Accepted Answer

Hello.

Do you select "With new resources (standard)" when creating CloudFormation?  
You must select this option to create a new resource.

I believe the error itself is similar to the one answered in the following Github issue.
