如何将请求从Lumen中的一个操作重定向到另一个操作

I have two controllers

App\Http\Controllers\Controller\StartController
App\Http\Controllers\Controller\Legacy\StartLegacyController

When I receive request at my first controller, I check if request contains version=legacy

if yes then I want to redirect that request to StartLegacyController@index Action

Else I'll process the request in StartController itself. Here's my code from StartController

public function index(Request $request)
{
    $version = $request->input('version', 'legacy');
    if ($version == 'legacy') {
        return Redirect::action('App\Http\Controllers\Legacy\StartLegacyController@index');
    }

    dd('OKK',$request->all());
}

I am getting

(1/1) RuntimeException
A facade root has not been set.

I Tried to remove Namespace, even put controller in the same namespace but it isn't working, will really appreciate any kind of help.

EDIT

Since Redirect::action() not working in this case I've come up with a temporary solution to my problem with as @Ali Mrj suggested

$router->get('/start', function (\Illuminate\Http\Request $request) use ($router) {
    $version = $request->input('version', 'legacy');
    if($version == 'legacy'){
        $controller = $router->app->make('App\Http\Controllers\Legacy\StartLegacyController');
        return $controller->index();
    } else{
        $controller = $router->app->make('App\Http\Controllers\StartPageController');
        return $controller->index($request);
    }
});

Will appreciate other solutions for the issue...

I think the following code will do it for you:

return redirect()->action('StartLegacyController@index');
