Error with expo-auth-session when migrating to SDK41 from SDK40

Summary

We are trying to migrate from SDK40 to the latest SDK41 but are now seeing this error when using expo-auth-session:

import * as AuthSession from 'expo-auth-session';
const result = await AuthSession.startAsync({authUrl, returnUrl: redirectUrl});

It is throwing this exception, which was working fine for us in SDK 40:

[TypeError: null is not an object (evaluating 'manifest.currentFullName')] For context, we use auth0 to do our auth. This worked well for us prior to SDK41.

Our configuration and setup for expo-auth-session we had followed when we first installed it seem to still be correct according to the latest docs here: https://github.com/expo/expo/tree/master/packages/expo-auth-session

We are on a bare workflow.

Any tips or ideas of what might be happening?

Managed or bare workflow? If you have ios/ or android/ directories in your project, the answer is bare!

Reproducible demo or steps to reproduce from a blank project

import * as AuthSession from 'expo-auth-session';

const authUrl = 'https://ourauthzerohostedsite.com'
  const redirectUrl = 'appName://login';

const result = await AuthSession.startAsync({authUrl, returnUrl: redirectUrl});

I saw an identical error message using an EAS built managed app and SDK 42. Similarly, running expo config --type public would print the correct currentFullName and originalFullName.

I was ultimately able to resolve the error by adding an explicit ‘currentFullName’ and ‘originalFullName’ to our app.json file.
