Unable to POST to tollfree_verifications.create - getting missing parameter even though it is included

[dodontommy]

Issue Summary

When trying to submit a tollfree_verification through the Ruby SDK, I get Missing required parameter *param* in the post body for any array params, so for OptInImageUrls and UseCaseCategories, even though those params are included and are of type Array. I am doing this through a sub account - by initializing the Twilio::REST::Client like so @sub_account_client ||= Twilio::REST::Client.new(ACCOUNT_SID, AUTH_TOKEN, sub_account_sid).

I've also embedded some output in twilio-ruby-6.5.0/lib/twilio-ruby/rest/messaging/v1/tollfree_verification.rb in the create and I can see that the OptInImageUrls and UseCaseCategories are present there.

Steps to Reproduce

1. Initialize client with a sub account SID
2. Call client.messaging.v1.tollfree_verifications.create(params)

Code Snippet

def sub_account_client
  @sub_account_client ||= Twilio::REST::Client.new(ACCOUNT_SID, AUTH_TOKEN, sub_account_sid)
end

USE_CASE_SUMMARY = 'Foo bar'
PRODUCTION_MESSAGE_SAMPLE_1 = "EXAMPLE 1 STOP TO OPT OUT"
PRODUCTION_MESSAGE_SAMPLE_2 = "EXAMPLE 2 STOP TO OPT OUT"
OPT_IN_IMAGE_URLS = ['valid_image_url', 'valid_image_url_2', 'valid_image_url_3'].freeze
sub_account_client.messaging.v1.tollfree_verifications.create(
  business_street_address: verification_params[:street],
  business_street_address2: verification_params[:street_2],
  business_city: verification_params[:city],
  business_state_province_region: verification_params[:state],
  business_postal_code: verification_params[:zip_code],

  business_contact_email: verification_params[:email],
  business_contact_phone: verification_params[:phone_number],
  additional_information: verification_params[:additional_information],
  business_name: verification_params[:business_name],
  business_website: verification_params[:business_website],
  notification_email: 'it@foo.net',
  use_case_categories: ['ACCOUNT_NOTIFICATIONS','EVENTS'],
  use_case_summary: USE_CASE_SUMMARY,
  production_message_sample: [PRODUCTION_MESSAGE_SAMPLE_1, PRODUCTION_MESSAGE_SAMPLE_2].join('; '),

  opt_in_type: 'WEB_FORM',
  message_volume: '1,000',
  tollfree_phone_number_sid: phone_number_sid
)
