api Login not giving expected feedback message

In my Project I am using Laravel-8, laravel-passport and spatie-permission for restful api. Already, I have this code in the Controller.

I have this controller

 public function adminLogin(Request $request)
 {
      if (auth('web')->attempt($request->only('email', 'password'))) {
         $user = Auth::guard('web')->user();
         if (!$user->hasRole('Super Admin')) {
              auth('web')->logout();
             return $this->sendError('Unauthorised.', ['error'=>'Unauthorised']);
         }

         $success['token'] =  $user->createToken('MyApp')-> accessToken;
         $success['name'] =  $user->name;

         return $this->sendResponse($success, 'User login successfully.');
     }
     else{
         return $this->sendError('Unauthorised.', ['error'=>'Unauthorised']);
     }
 }:

If the logged in user is not 'Super Admin' Role, it should return:

return $this->sendError('Unauthorised.', ['error'=>'Unauthorised']);

The logged in user is 'Super Admin', yet it returns the error.

'Super Admin' is part of the current user's role, yet I am getting this feedback:

{"success":false,"message":"Unauthorised.","data":{"error":"Unauthorised"}}

It has to do with this line:

   if (!$user->hasRole('Super Admin')) {
      auth('web')->logout();
     return $this->sendError('Unauthorised.', ['error'=>'Unauthorised']);
   }

database dump

   CREATE TABLE `roles` (
     `id` bigint(20) UNSIGNED NOT NULL,
     `name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
     `guard_name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
     `created_at` timestamp NULL DEFAULT NULL,
     `updated_at` timestamp NULL DEFAULT NULL
   ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;


   INSERT INTO `roles` (`id`, `name`, `guard_name`, `created_at`, `updated_at`) 
   VALUES
   (1, 'Super Admin', 'web', '2019-11-13 12:11:38', NULL),
   (2, 'Employee', 'web', '2019-11-13 12:11:38', NULL),
   (3, 'HOD', 'web', '2019-11-13 12:11:38', NULL);


   CREATE TABLE `model_has_roles` (
     `role_id` bigint(20) UNSIGNED NOT NULL,
     `model_type` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
     `model_id` bigint(20) UNSIGNED NOT NULL
   ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

   INSERT INTO `model_has_roles` (`role_id`, `model_type`, `model_id`) VALUES
   (1, 'App\Models\User', 1),
   (2, 'App\Models\User', 1);

What could be the problem and how do I get it resolved?

Thanks
