Apparent use of outdated savon API in service.rb

[sidoh]

I'm using the same code I linked in the other issue (#14).

I may be missing something, but it seems that ~L278 of service.rb is using an outdated savon API. I get this stacktrace:

I tried downgrading the version of savon to no avail. Both 2.7.0 and 2.0.0 appear to have the same issue.

Switching the referenced playful code to use this:

              response = @soap_client.call(action_name.to_s,
                                           {soap_action: "#{st}##{action_name}",
                                            attributes: {'xmlns:u' => st}}) do
                message(params) unless params.nil?
              end

instead of:

            response = @soap_client.call(action_name.to_s) do |locals|
              locals.message_tags 'xmlns:u' => @service_type
              locals.soap_action "#{st}##{action_name}"
              #soap.namespaces["s:encodingStyle"] = "http://schemas.xmlsoap.org/soap/encoding/"

              unless params.nil?
                raise ArgumentError,
                  'Method only accepts Hashes' unless params.is_a? Hash
                soap.body = params.symbolize_keys!
              end
            end

seems to fix the issue.
