AnonymousAuthenticationProvider causes HTTP layer to throw error

auth_provider = MicrosoftKiotaAbstractions::AnonymousAuthenticationProvider.new()
request_adapter = MicrosoftKiotaFaraday::FaradayRequestAdapter.new(auth_provider)
client = Client::PostsClient.new(request_adapter)

all_posts = client.posts_by_id("5").get.resume

This results in the following error:

/home/jasonjoh/.rbenv/versions/3.1.2/lib/ruby/gems/3.1.0/gems/microsoft_kiota_faraday-0.11.0/lib/microsoft_kiota_faraday/faraday_request_adapter.rb:52:in `block in send_async': undefined method `resume' for nil:NilClass (NoMethodError)

        @authentication_provider.authenticate_request(request_info).resume

As a test, I modified anonymous_authentication_provider.rb, changing the authenticate_request to:

def authenticate_request(request)
  Fiber.new do
  end
end

And that resolved the error.

Start with anonymous_authentication_provider.rb and the call at faraday_request_adapter.rb:52, then reproduce the issue with the PostsClient snippet in the report. Check the return from authenticate_request and verify that the anonymous provider no longer causes the HTTP layer to call resume on nil and that the request completes successfully.
