{proxy+} swagger definitions

[blackwj]

Hi I've been trying to use the AWS generic proxy swagger open API definition from the AWS site and it always gives the error 'Declared path parameter "proxy+" needs to be defined as a path parameter at either the path or operation level'  Below is the definition.  What's the issue?

openapi: 3.0.0

paths:
  '/{proxy+}':
    x-amazon-apigateway-any-method:
      parameters:
        - name: proxy
          in: path
          required: true
          schema:
            type: string
      responses: {}
      x-amazon-apigateway-integration:
        responses:

            statusCode: '200'
        requestParameters:
          integration.request.path.proxy: method.request.path.proxy
        uri: 'http://petstore-demo-endpoint.execute-api.com/petstore/{proxy}'
        passthroughBehavior: when_no_match
        httpMethod: ANY
        cacheNamespace: rbftud
        cacheKeyParameters:
          - method.request.path.proxy
        type: http_proxy

    variables:
      basePath:
        default: /test

The issue is that the name of the parameter is 'proxy' but the path is defined as /{proxy+} suggesting that the name of the parameter is 'proxy+' One of those needs to be changed.

Hi Ron, 

As suggested, I did change name to proxy+ but i am stilling getting the same error

Can you please edit the reply or add a new one with the API definition appearing in a code block? Otherwise the indentation is lost which is critical to understanding possible issues. Thanks.

The parameters aren't really defined under the operation, but under the extension 'x-amazon-apigateway-any-method'. This may be good for AWS but it's not how the specification works. The parameters need to be defined directly under the path '/{proxy+}'.

hi ron,

can give provide me a working example where you have used {proxy+} path in swagger definition. Because i am not able to get through that error still.
