Question

The following code I put for x-amazon-apigateway-integration, please let me know if I am missing something. Thanks

  x-amazon-apigateway-integration:
    httpMethod: post
    type: aws
    uri:
      Fn::Sub: 
        - arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${FunctionArn}/invocations      
        - { FunctionArn: !GetAtt  PriceAPIFunction.Arn}
    responses:
      default:
        statusCode: '200'

Answer 1

The ${AWS::Region} substitution is not supported - only the function name can be substituted. see https://github.com/awslabs/serverless-application-model/issues/79
