[RUBY] Json object defined with `additionalProperties` in swagger.yml gets validated against `array` datatype instead of `hash`

[aakanksha-sib]

Description

I have a JSON input object with one of its keys as another object but variable key-value pairs:

parentObject:
    type: object
    properties:
      key1:
        type: object
        additionalProperties:
          description: Name of custom property
          type: string
          example: 'Ellie'

In generated ruby wrapper, this key1 object is getting validated against array datatype instead of hash which is causing the request failure.
For example, following piece of code is not working:

input_params = MyApi::ObjectCreationApi.new({'key1'=> {'name'=>'abc', 'place'=>'bcd'}})
MyApi::ObjectsApi.new.create_object(input_params)

Swagger-codegen version

2.2.3

Suggest a fix/enhancement

Type of key1 should be matched against hash not array.

Can you try the latest stable version 2.3.0 instead? If I remember correctly, the issue has been addressed.

Hi @wing328 , I tried the same with v2.3.0 but issue still persists.
