Laravel validation on Http request

I wrote this part of Api:

public function store(Request $request)
{
    $this->validate($request, [
            'citizenship' => 'required',
            'country' => 'required'
    ]);
...

and I am sending a Post request with Postman not passing one of the required field and I don't see any error response, but it just redirect me to the home page of the application. How can I grab the error message?
