Parameter hash sent to RestClient not working

[erithmetic]

When I perform a Mailgun().routes.create or Mailgun().routes.update command, I get the following error:

{                                           
  "message": "'action' parameter is missing"
}                                           

I debugged the problem and found that at https://github.com/HashNuke/mailgun/blob/master/lib/mailgun/base.rb#L71 RestClient is not recognizing the parameters hash passed to it and not posting parameters to Mailgun, even though it has data.

Here's my test code:

  def self.create(pattern)                                                     
    mailgun.routes.create "Catch-all route for #{ENV['MAILGUN_ROUTE_DOMAIN']}",
      DEFAULT_PRIORITY,                                                        
      [:match_recipient, pattern],                                             
      [[:forward, endpoint_url], [:stop]]                                      
  end                                                                          

  # ...

  describe '.create' do                                         
    let(:pattern) { '.*@.*.test.com' }                      

    it 'creates a route' do                                     
      VCR.use_cassette :email_route_create do                   
        EmailRoute.create pattern                               

        expect(EmailRoute.existing_route(pattern)).to be_present
      end                                                       
    end                                                         

  end                                                           

Here's a dump of my VCR cassette during a create:

Did you ever resolve this?

[erithmetic]

No I found another way to set up routes

Right, so it's not the code, it's the Multimap hash not working with Restclient. Not sure if it's version specific or not.
