Cannot access protected property parameters laravel 5.5

I'm trying to get the parameters from the $request like following: $request->request->parameters but i get this error Cannot access protected property Symfony\Component\HttpFoundation\ParameterBag::$parameters.

Now I know that with a protected property I would have to use $request->request->parameters() but when i do this i get the next error: Call to undefined method Symfony\Component\HttpFoundation\ParameterBag::parameters().

I'm using laravel V5.5

anyone know what i can try to fix this and get the parameters i sent from my blade?
