Problem with Yaml key in Resources section (Cloudformation)

Serverless Framework
1

As part of my resources section I’m creating an API Gateway method (independent of lambda). I’m trying to set the IntegrationResponses using the Yaml like so:

Integration:
      IntegrationResponses:
        - StatusCode: 200
          ResponseParameters:
            method.response.header.Content-Type: integration.response.header.Content-Type

This is valid Cloudformation Yaml. However Serverless upon deploy converts it to JSON and uploads to S3. Looking at the JSON output the result is:

"ResponseParameters": {
  "method.response.header.Content-Type": "integration.response.header.Content-Type",
  "method": {
    "response": {
      "header": {
        "Content-Type": "integration.response.header.Content-Type"
      }
    }
  }
}

It appears that during the conversion to JSON the Yaml key is being separated by the dots and turned into a nested object. This is no longer valid Cloudformation and fails with

An error occurred while provisioning your stack: ServiceWorkerMethod
     - Value of property ResponseParameters must be an object with String (or simple type) properties.

How can I prevent this conversion. The expected output is also present, so how do I stop that nested object from being created. I have tried many many combinations of quotes and formatting with no luck.

Any thoughts?
Thanks
