private method `define_method'

[rafayet-monon]

NoMethodError: private method `define_method' called for OneSignal::Notification::Headings:Class

error showing when I call

OneSignal::Notification::Headings.new(en: 'Hello!', it: 'Ciao!')

doing this in OneSignnal::Automap fixes it, is this the right way?

def create_readers **attributes
      attributes.keys.each do |k|
        self.class.send(:define_method, k) do
          attributes[k]
        end
    end
end

Also in response

NoMethodError: private method `attr_reader' called for OneSignal::Responses::Notification:Class

usinng the mattr_reader instead attr_reader fixes it in OneSignal::Responses::BaseResponse. is this the right way?

def initialize attributes = {}
        @attributes = attributes.deep_symbolize_keys
                                .keep_if { |k, _v| self.class::ATTRIBUTES_WHITELIST.include?(k.to_sym) }
        self.class.mattr_reader(*self.class::ATTRIBUTES_WHITELIST)
      end

hi, I've got this issue

NoMethodError: private method `define_method' called for OneSignal::Notification::Headings:Class
Did you mean?  redefine_method
from .../gems/onesignal-ruby-0.3.0/lib/onesignal/auto_map.rb:7:in `block in create_readers'

as @rafayet-monon has described above

are there any workarounds rn to send notifications with current gem version?
or when we should expect to have new version with fixed methods?

(I was following readme to send notification)
thanks
