Validation not returning errors Laravel 7 - php

Question

I have been trying to validate input fields on a project I'm working on. It has not been returning the validation errors. Also each time I remove the validation and I attempt to submit the form data after filling it, it returns an undefined index error.
This is my Controller
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Mail;
use Illuminate\Support\Facades\staffLogin;
use Validator;
use App\Country;
use App\Category;
use App\User;
use App\Resume;
use Image;
use Auth;
use Session;
use DB;
class EnrolController extends Controller
{
public function home(){
$title = 'home';
return view('staff.home');
}
public function profile(Request $request){
$title ='profile';
$user_id = Auth::user()->id;
$user_name = Auth::user()->name;
$user_email = Auth::user()->email;
$userDetails = User::find($user_id);
if($request->isMethod('post')){
$data = $request->all();
// echo "<pre>"; print_r($data); die;
$data = request()->validate([
'category_id' => 'required',
// 'firstname' => 'required|regex:/^[\pL\s\-]+$/u|max:255',
// 'lastname' => 'required|regex:/^[\pL\s\-]+$/u|max:255',

Try the following
use use Illuminate\Support\Facades\Validator;
//...
$validator = Validator::make($request->all(), [
'category_id' => 'required',
...
]);
if ($validator->fails()) {
return redirect()->back()
->withErrors($validator)
->withInput();
}
$data = $validator->validated();
