AWS SAM: The REST API doesn't contain any methods

Question

Hello,  
  
I'm getting started with AWS SAM, and built a simple deployment based on  this example from Amazon:  
 .  
  
My (very similar) code is available there:

When deploying, I am getting the following message: **The REST API doesn't contain any methods (Service: AmazonApiGateway; Status Code: 400; Error Code: BadRequestException)**  
  
Checking online for this error, I find many occurrences, but they seem to be related to manually creating a deployment, which I am not doing here.  
  
My code being extremely similar to the Amazon example, I cannot pinpoint the error.  
  
Thanks.

Answer

I did continue investigating the issue, and it seems that the error is indeed mine: Swagger definition requires to define methods in the body directly ; I just wanted to use it to create the resource policy.  
  
Looks like I'm waiting for this:
