x-amazon-apigateway-integration not added to swagger

[kjetilge]

I've followed your tutorial, and I've gotten the Lambda function to work when testing and when visiting: https://img2.cloudfront.net/prod/resize/500x500/bilde2.jpg - the image is produced in S3 but I get redirected to img2.execute-api.eu-west-1.amazonaws.com/prod/resize/500x500/img-resized.s3-website-eu-west-1.amazonaws.com/500x500/bilde2.jpg

Also: the following is not generated in my Swagger file

        "x-amazon-apigateway-integration": {
          "responses": {
            "default": {
              "statusCode": "302",
              "responseParameters": {
                "method.response.header.Location": "integration.response.body.location"
              }
            }
          },
          "requestTemplates": {
            "application/json": "{ \"size\": \"$input.params('size')\", \"image\": \"$input.params('image')\" }"
          },
          "uri": "arn:aws:apigateway:us-east-1:lambda:path/2015-03-31/functions/arn:aws:lambda:us-east-1:150130051736:function:resize/invocations",
          "httpMethod": "POST",
          "type": "aws"
        }
      }

After the image is generated I can se it in a browser at: http://img1.cloudfront.net/500x500/bilde2.jpg

Any hints to what's going on ?
