[expo-facebook] Crashes standalone iOS app on logInWithReadPermissionsAsync

Expo SDK
1
  • SDK: 41
  • Platform: iOS, Managed but standalone (deployed to TestFlight)
  • expo-facebook: 11.0.5

Problem: Facebook.logInWithReadPermissionsAsync crashes my TestFlight build. The moment the function runs, my app immediately crashes and I am back on the home screen.

The same code works well in Expo Go. I have read others having similar issues in the past, and they could pass a parameter behavior = "web" to logInWithReadPermissionsAsync. But, the behavior parameter seems to have been removed.

What’s causing this? Would love to hear from anyone that has experienced this, or something similar, before.

signInWithFacebook.js

export async function signInWithFacebook() {
  await Facebook.initializeAsync({
    appId: process.env.FACBEOOK_APP_ID,
    appName: process.env.FACEBOOK_DISPLAY_NAME,
  });
  const { type, token } = await Facebook.logInWithReadPermissionsAsync();
  // ☝️ This is where it crashes
  // ...

app.config.js

import "dotenv/config";

export default {
  facebookScheme: process.env.FACEBOOK_SCHEME,
  facebookAppId: process.env.FACBEOOK_APP_ID,
  facebookDisplayName: process.env.FACEBOOK_DISPLAY_NAME,
  // ...

Happening for me too… on a bare workflow

same as mentioned in the above - Tried versions 9/10/11 - starting to think its something to do with my xcode setup.
