注销在Laravel 5.3.10中不起作用

I am using Laravel 5.3.10. I am trying to use auth0. My route for logout in web.php is

Route::get('/logout', function() { Auth::logout(); });

But the logout is not working. It is giving me below error.

ApiException in Authentication.php line 47: client_id was not set.

Could anyone help me in this regard ??
