Laravel 5.8 register redirect - laravel

Question

I'm using Laravel 5.8, still new to PHP and Laravel. When I register, it returns the user in JSON format which is normal from the Register Users.php register function. However, I have a redirectTo() function which should take care of the redirect and redirect the user to some pages a specified, but it's not working. I've tried overriding the redirectPath() function as well which isn't working.
The redirect works perfectly for the login controller.
Any solution or pointers would be appreciated. See RegisterController below.
namespace App\Http\Controllers\Auth;
use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Http\Request;
use Auth;
class RegisterController extends Controller
{
use RegistersUsers;
/**
* Where to redirect users after registration.
*
* #var string
*/
//public $redirectTo = '/home';
protected function redirectPath()
{
$role = Auth::user()->role;
if ($role === 'candidate') {
return '/candidate_dashboard';
} elseif ($role === 'employer') {
return '/employer_dashboard';
} elseif ($role === 'contractor') {
return '/contractor_dashboard';
}
}
public function __construct()
{
$this->middleware('guest');
}
protected function validator(array $data)
{
try {
return Validator::make($data, [
'first_name' => ['required', 'string', 'max:255'],
'last_name' => ['required', 'string', 'max:255'],
'role' => ['required', 'string', 'max:50'],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
'password' => ['required', 'string', 'min:8', 'confirmed'],
]);
} catch (Illuminate\Database\QueryException $th) {
return back()->withError($th->getMessage())->withInput();
}
}
protected function create(Request $data)
{
try {
return User::create([
'first_name' => $data['first_name'],
'last_name' => $data['last_name'],
'role' => $data['role'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
]);
} catch (Illuminate\Database\QueryException $th) {
return back()->withError($th->getMessage())->withInput();
}
}
}
