ArgumentError: wrong number of arguments (1 for 2) when creating ups.ship object

[dazl]

I get an ArgumentError: wrong number of arguments (1 for 2) when creating a ups.ship object as in the code snippet below.

I get a different trace depending on which ruby version I am using but always the same error.

Thanks in advance for any help, david

This is what I wrote in irb -- I am not sure I am writing the service_type the correct way or if I am missing some required parameters.

require 'shippinglogic'
ups = Shippinglogic::UPS.new( ....removed.... ,{:test=>true})
shipment = ups.ship(:shipper_name => 'Test Shipper',
:shipper_company_name => 'Shipper Company Name',
:shipper_phone_number => '9012638716',
:shipper_streets => 'Address Line 1',
:shipper_city => 'Austin',
:shipper_state => 'TX',
:shipper_postal_code => '73301',
:shipper_country => 'US',

:recipient_name => 'Test Recipient',
:recipient_company_name => 'Recipient Company Name',
:recipient_phone_number => '9012637906',
:recipient_streets => 'Address Line 1',
:recipient_city => 'Herndon',
:recipient_state => 'VA',
:recipient_postal_code => '20171',
:recipient_country => 'US',
:recipient_residential => true,

:package_weight => 10.0,
:package_length => 20,
:package_width => 20,
:package_height => 10,

:service_type => "02")
