[Ruby] Nested resources are not using datatype defined in documentation.

I am working with an API and the datatype is created correctly for c#

I have tried for Ruby and Typescript-fetch and it is returning generic values.

I can't see what I am doing wrong for Ruby or Typescript.

docker pull swaggerapi/swagger-codegen-cli-v3:3.0.42

docker run -it --rm -v ${PWD}:/local swaggerapi/swagger-codegen-cli-v3 generate \
    -i /local/docs/api/tes.yml \
    -l ruby \
    -o /local/lib/test\

The data model generated for user looks like this:

require 'date'

module MobileDataAnywhere
  class User
    attr_accessor :devices

    # Maximum of devices allowed for the current client
    attr_accessor :number_of_devices_allowed

    # Attribute type mapping.
    def self.openapi_types
      {
        :'devices' => :'Object',
        :'number_of_devices_allowed' => :'Object'
      }
    end

As a matter of fact, when the object is replaced manually to "Array", works perfectly.

Start by reproducing the issue with the provided Docker command and documentation.yml, then inspect the generator templates responsible for the Ruby User model's nested devices property and number_of_devices_allowed type. Compare the generated Ruby and working C# models; done means nested properties use their documented types instead of generic Object values.
