Is your ArticlesController in App\Http\Controllers namespace?

I am facing the same issue trying to redirect guests to HomeController index action. Here is my code with Laravel 5.0.27:

Route::get('/', ['as' => '/', function() {
    if (Auth::guest())
        return redirect()->action('HomeController@index');

    $loggedInHomeUrl = ...;
    return redirect($loggedInHomeUrl);
}]);

The error message says: InvalidArgumentException thrown with message "Action App\Http\Controllers\HomeController@index not defined."

My controller namespace is

namespace App\Http\Controllers;

I can't see what is wrong. I tried invoking redirect()->action(...) with many other controllers and actions but I can't manage to make this method work.

Could anyone point me to the error in the code above?

Having the same issue... everything looks fine... but it isn't working...

I just had this problem, it seems you need to add the controller action as a route in your routes.php file and then you're able to map the controller action through the redirect.

You can declare a route like:

Route::get('home', 'HomeController@index');

And then:

Route::get('/', function() {
    if (Auth::guest()) {
        return redirect('home');
    }

    $loggedInHomeUrl = 'someUrl';

    return redirect($loggedInHomeUrl);
});
