Null is not an object (evaluating '_reactNative.NativeModules.RNPinch.fetch')

[AlbertoGuastalla]

Hi, I was trying to pin a self signed certificate inside my react-native app using your "react-native-pinch" library. The problem is that when I launch the fetch, I get an error like this: "null is not an object (evaluating '_reactNative.NativeModules.RNPinch.fetch')". I searched the internet and found nothing.

Thanks in advice.
