Option keepSessionInfo: 'true' does not work.

[unitydevadtest]

Until I implement better solution I still keep returnTo in session to return user to the page where he initiated login. This is possible with keepSessionInfo: 'true' option, it works with google and facebook but not with apple. After apple callback session is just deleted.

Is there any way to fix it?

You can pass a redirection URL through the state (https://developer.apple.com/documentation/sign_in_with_apple/clientconfigi/3230956-state).

e.g.

// in auth route:
passport.authenticate('apple', { state:JSON.stringify(state), nonce:nonce })(req,res,next);

// passport callback:
passport.use(
    'apple',
    new AppleStrategy({ ....  }, (req, accessToken, refreshToken, profile, done) => {
        let state = {};
        try {
            state = JSON.parse(req.body.state);
        } catch (e) {
            console.error('ignoring un-parseable apple sign-in state', e);
        }

        // state.redirectTo is your redirection URL, but it might have been
        // modified by the user (and is visible to them) so don't put secrets
        // in it or trust its value to be secure!

        // ... the rest of your sign-in logic ...
