Timeout using auth0.webAuth.authorize in React Native

Hello, this is my first time embarking on a React Native project, and I am still relatively new to developing as a whole, forgive me for my brevity.

I am also using Typescript for my project, so I have modified some of the code from the guides for it.

I am trying to integrate Auth0 login into my app, at first I followed the set-up guide from the react-native-auth0 Documentation. After clicking on the Login button, it correctly redirects me to the universal login page, but after logging in it simply returns back to my Landing page instead of Home, and I realized that the [user] object was null.

Then, I’ve tried following this guide here: Get Started with Auth0 Authentication in React Native Android Apps. The same issue occurs, and I’ve caught the error after running auth0.webAuth.authorize, which returned a Timeout error.

Here is the code I tried for the context:

import React, {useState, useEffect, FC, useContext} from 'react';
import {REACT_APP_AUTH0_DOMAIN, REACT_APP_AUTH0_CLIENT_ID} from '@env';
import SInfo from 'react-native-sensitive-info';
import Auth0 from 'react-native-auth0';
import jwtDecode from 'jwt-decode';

const auth0 = new Auth0({
  domain: REACT_APP_AUTH0_DOMAIN,
  clientId: REACT_APP_AUTH0_CLIENT_ID,
});

export interface IAuth {
  loading: boolean;
  loggedIn: boolean | null;
  login: () => Promise<void>;
  logout: () => Promise<void>;
  userData: {
    name: string;
    picture: string;
  } | null;
}

const AuthContext = React.createContext<IAuth | null>(null);
export const useAuthContext = () => {
  const val = useContext(AuthContext);

  if (val === null) {
    throw new Error('AuthContext used outside of provider!');
  }
  return val;
};

export const AuthContextProvider = (props: any) => {
  const [loading, setLoading] = useState(true);
  const [loggedIn, setLoggedIn] = useState<boolean | null>(null);
  const [userData, setUserData] = useState<{
    name: string;
    picture: string;
  } | null>(null);

  const getUserData = async (id?: string) => {
    const idToken = id ? id : await SInfo.getItem('idToken', {});
    type customJwtPayload = {name: string; picture: string; exp: number};
    const {name, picture, exp} = jwtDecode<customJwtPayload>(idToken);

    if (exp < Date.now() / 1000) {
      throw new Error('ID token expired!');
    }

    return {
      name,
      picture,
    };
  };

  useEffect(() => {
    (async () => {
      try {
        const user_data = await getUserData();
        if (user_data) {
          setLoggedIn(true);
          setUserData(user_data);
        }
      } catch (err) {
        setLoggedIn(false);
      }
    })();
  }, []);

  // Executed just after the user logs in
  useEffect(() => {
    (async () => {
      try {
        if (loggedIn) {
          const user_data = await getUserData();
          if (user_data) {
            setLoggedIn(true);
            setUserData(user_data);
          }
        }
      } catch (err) {
        alert(`Error logging in use effect ${err}`);
      }
    })();
  }, [loggedIn]);

  const login = async () => {
    try {
      const credentials = await auth0.webAuth.authorize({
        scope: 'openid email profile',
      });

      await SInfo.setItem('idToken', credentials.idToken, {});
      const user_data = await getUserData(credentials.idToken);
      setLoggedIn(true);
      setUserData(user_data);
    } catch (err) {
      alert(`Error logging in ${err}`);
    }
  };

  const logout = async () => {
    try {
      await auth0.webAuth.clearSession({});
      await SInfo.deleteItem('idToken', {});
      setLoggedIn(false);
      setUserData(null);
    } catch (err) {
      alert(`Error logging out ${err}`);
    }
  };

  const value = {
    loading,
    loggedIn,
    login,
    logout,
    userData,
  };

  return (
    <AuthContext.Provider value={value}>{props.children}</AuthContext.Provider>
  );
};

Many thanks in advance.

Did you manage to resolve this timeout issue? I have same kind of problem on my hands…

Kind of. For myself, the issue was the emulator I was using to debug the app (Android Studio). I just used my physical phone to download the app, and it worked. Exporting and downloading the release .apk onto other devices or Bluestacks also works.

Not too sure why the emulator on Android Studio specifically causes this error, and if this is the cause of your issue as well.
Hope this helps!

Am having the same issue. The Universal login page is opened only on first sign in/up, subsequent attempts to login only open a white screen and in both scenarios, there is no redirecting to the app. I followed the same guide. Any help would be much appreciated
