I’ve seen a few posts of a similar problem but none of them provided a solution for me.

I’m getting the `a0.credential_manager.invalid: Cannot read property 'hasValidAuth0InstanceWithConfiguration' of null` error on both android and ios.

I’ve followed the Quickstart guide for React Native and I’m aware that the `react-native-auth0` SDK doesn’t work for Expo Go. I’m using a React Native app with some Expo modules (bare workflow). Does that mean the SDK won’t work for me too?

Thanks in advanced!

Hi @jiravinyoo,

Welcome to the Auth0 Community!

You can use the react-native-auth0 SDK with your Expo modules if you are using the bare workflow.

It might be worth trying to use the [Auth0 React Native quickstart](https://auth0.com/docs/quickstart/native/react-native/interactive) without your Expo modules first to verify that everything works. If you have confirmed this works, you can continue adding the Expo modules and see how that goes.

Let me know if you continue experiencing issues.

Thanks,  
Rueben
