getting error "undefined method `map' ..." when trying to PUT to /audience_members/<email>

[michel...@gmail.com]

I'm trying to update some user data but am running into an error every time.

So I have an existing user:

$ MADMIMI.memberships("te...@test.com")

 => {"lists"=>{"list"=>{"name"=>"All Users", "id"=>"771443", "subscriber_count"=>"159", "display_name"=>""}}} 

But if I try to update that user by issuing a PUT request to http://api.madmimi.com/audience_members/te...@test.com

with body:

name=abc&username=XXX&api_key=XXX

the response I get back is:

"{\"error\":\"undefined method `map' for nil:NilClass\",\"success\":false}" 

any idea what that could be?  (full ruby code below)

thanks

I'm using the madmimi ruby gem which doesnt have a PUT method so I added one:

class MadMimi

  MIMI_UPDATE_PATH = ' /audience_members/%email%'

  

  def do_put_request(path, options = {})

    options = options.merge(default_opt)

    resp = href = ""

    

    http = Net::HTTP.new(BASE_URL, 80)

    begin

      http.start do |http|

        req = Net::HTTP::Put.new(path)

        req.body = URI.encode_www_form(options)

        req.content_type = 'application/x-www-form-urlencoded'

        response = http.request(req)

        resp = response.body.strip

      end

    rescue SocketError

      raise "Host unreachable."

    end

  end

  

  def audience_update(email, params)

    do_put_request(MIMI_UPDATE_PATH.gsub('%email%', email), params)

  end

end

If I then run from the console:

$ response = MADMIMI.audience_update("te...@test.com", {"name" => "abc"})

$ JSON.parse(response)

=> {"error"=>"undefined method `map' for nil:NilClass", "success"=>false}
