Laravel 5 geting InvalidStateException in AbstractProvider.php

I wasn't comfortable with just commenting out code that signalled an error (as in @Dipesh Shihora's answer), so I dug a little further. I discovered that the error is caused (in my case at least) by a problem with sessions.

My dev server is set up according to the instructions given in this answer. Basically, I am "spoofing" Google by using a callback URL which looks like a publicly-accessible address.

The InvalidStateException problem was appearing for me because I was visiting my login page at http://localhost/login and redirecting to Google's login page, which then returned me to http://myapp.example.com/callback. The problem is that the session key is stored in a cookie - it was originally a cookie for http://localhost, but when I redirected to a different URL, the cookie (and hence the session key) was inaccessible. Thus, the session state value was non-existent after the update and the exception was thrown.

The solution? Ensure that all my browsing on the dev machine was done at http://myapp.example.com and not at http://localhost.

It work on my website , just call ->stateless() before get user

Socialite::driver('facebook')->stateless()->user()
Socialite::driver('google')->stateless()->user()

Try setting the correct values in the 'domain' field of config/session.php and the 'url' field of the config/app.php. This seems to have done the trick for me. I noted that the value in session.php should be without http://, while the one in app.php should be with http://.

Also, I recommend you follow this guide: https://laracasts.com/series/whats-new-in-laravel-5/episodes/9. It's extremely helpful and clear.
