How to deploy a CDK synthesized template using cloudformation directly?

[jabalsad]

Hi,

I need to deploy our CDK synthesized CFN template directly using the cloudformation create-change-set/create-stack APIs. However, when supplying the generated template, the CFN CLIs raise an error:

› aws cloudformation create-change-set --stack-name test-stack --change-set-name test --template-body cdk.out/test.template.json

An error occurred (ValidationError) when calling the CreateChangeSet operation: Template format error: unsupported structure.
