Laravel 5.5空对象

Good afternoon guys, I'm having an issue I don't know if you have the same trouble, I upgrade my Laravel project and now all routes like this

Route::get('detail/client/{client}', "controller@method")

are breaking everything because the object instanced in the controller comes empty...

public function detail(FileRequest $request, Client $client){

 dd($client) // empty object
}

If someone can help me with this please. If I remove the Client model and make the dd then return the ID of the object i.e "594"

You haven't written base Laravel version you are upgrading from, but I think it might have something in common with \Illuminate\Routing\Middleware\SubstituteBindings::class middleware.

Make sure you have it in middlwareGroups like this:

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        // \Illuminate\Session\Middleware\AuthenticateSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
        \App\Http\Middleware\VerifyCsrfToken::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class, // <- this is the line you should have
    ],
    'api' => [
        'throttle:60,1',
        'bindings',
    ],
];

in app/Http/Kernel.php file

and also make sure the routes you have problem are in web middleware group.
