It seems to be related with the returned json from the expo server.

My code looks like this

   client = Exponent::Push::Client.new(gzip: true)
    messages = Device.all.map { |device|
      {
          to: device.device_token,
          sound: "default",
          body: "Todays news is ready for you"
      }
    }

    puts "Messages to deliver: " + messages.count.to_s
    puts messages.to_s

    if messages.count > 0
      messages.each_slice(25) do |slide|
        resp = client.publish slide
        puts resp.inspect
      end
    end
  end

I believe I have resolved this in #29. I was experiencing a similar situation

Hi @lsmolic I am experiencing similar issue.

Can you clarify on how to use your modifications? I saw that it has not been merged into master yet.
Is it ready for production?

Thanks in advance

@cassio-nuke I've resolve this. It was an awful error with the Http Request library, but it is resolved in my tests. I need help getting my PR merged. Do you know who has merge ability?
