I'm trying to enable CORS in my AWS SAM app. Here is the snippet from my template.yaml:

Globals:
  Api:
    Cors:
      AllowMethods: "'*'"
      AllowHeaders: "'*'"
      AllowOrigin: "'*'"

Resources:
  MyApi:
    Type: AWS::Serverless::Api
    Properties:
      StageName: prod
      Auth:
        Authorizers:
          MyCognitoAuthorizer: ...

  getByIdFunc:
    Type: AWS::Serverless::Function
    Properties:
      Handler: src/handler.handle
      Events:
        ApiEvent:
          Type: Api
          Properties:
            Path: /{id}
            Method: GET
            RestApiId: !Ref MyApi

根据此Using CORS with AWS SAM和https://github.com/aws/serverless-application-model/issues/373，cors配置应该可以工作，但不幸的是API响应上没有设置标头，如下所示。

< HTTP/2 200 
< content-type: application/json
< content-length: 770
