Unknown error getting products react-native-iap - react-native

I have days trying to implement in app purchase in React Native without success. I was trying using In-app purchases from Expo and right now with react-native-iap and I'm facing this error:
error code: E_UNKNOWN. error message: UNKNOWN_ERROR
Subscription file
Apple Connect Info
App.tsx file:

This bug occurs on ios Simulator, after hours and hours of search and no solutions, what you need to do is Running the app on real device.
connect ios device to your computer and run it on the real device and you will see your in-app products

You cannot test in app purchase in simulator.
There is way to test in app purchase in simulator
Using StoreKit we can test in app purchase in simulator please look at this

I runned a react native app in different devices. But I got a different result

I runned a react native app in different devices.A device is iOS 9 and another is iOS 10. The device iOS 9 will encounter a error that could not connect to development server.The device iOS 10 can run successfully.I use react native 0.4.1. I will show you more informations if you need. I don't know what should I show.And you can tell me some ideas if you know some possible reason
I believe all the devices must be connected to the same Apple Developer account. Check if both of your devices have the same Apple ID and try to run them through Xcode.
Also make sure you follow all the steps in these guides
Running On Device
Launching Your App on Devices
If it doesn't work but you are still able to install the app, try to run the app with Wi-Fi while being on the same network as your mac, here is the guide on how to do that
Cheers!
