Driver [] is not supported

You see, I'm doing a url with which to see images of a table of plants. web.php:

Route::get('/images/{path}/{attachment}', function($path, $attachment){
    $storagePath = Storage::disk($path)->getDriver()->getAdapter()->getPathPrefix();
    $imageFilePath = $storagePath . $attachment;

    if(File::exists($imageFilePath)){
        return Image::make($imageFilePath)->response();
    }
});

The function in plantas.php:

public function rutas(){
        return "images/fotos/" . $this->foto;
    }

And the code in filesystems.php:

'planta' => [
            'driver' => 'local',
            'root' => storage_path('app/fotos'),
            'url' => env('APP_URL').'/storage',
            'visibility' => 'public',
        ],

After this, I have in \storage\app\fotos an image called cactus.jpg , so after activating php artisan serve , I write http://127.0.0.1:8000/images/fotos/cactus.jpg

What will be failing?

Edit: I have tried to make the code $storagePath before dd("Hola")

That works, but if it is before $imageFilePath , the error message is skipped again. In other words, the error is in the code $storagePath = Storage::disk($path)->getDriver()->getAdapter()->getPathPrefix();
