Spartie - User does not have the right roles. Laravel multi guard - laravel-8

Question

I'm getting this error "message": "User does not have the right roles.", "exception": "Spatie\Permission\Exceptions\UnauthorizedException", I am using spatie package https://github.com/spatie/laravel-permission
This error occurs anytime I try accessing an api route protected with ['role:admin'] middleware. I'm using passport for API authentication and Spatie for ACL. I used multi guards. Everything works fine without the spatie middleware but I want to protect certain routes based on user roles
This is my config/auth.php
'defaults' => [
'guard' => 'api',
'passwords' => 'users',
],
'admin' => [
'driver' => 'eloquent',
'model' => Admin::class,
],
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'passport',
'provider' => 'users',
'hash' => false,
],
'admin' => [
'driver' => 'session',
'provider' => 'admins',
],
],
This is my kernel.php
protected $routeMiddleware = [
.......
'role' => \Spatie\Permission\Middlewares\RoleMiddleware::class,
'permission' => \Spatie\Permission\Middlewares\PermissionMiddleware::class,
'role_or_permission' => \Spatie\Permission\Middlewares\RoleOrPermissionMiddleware::class,
];
When registering a user, I assign the role of admin like this in my AuthController. The 'admin' role gets assigned to the User successfully but I still get "User does not have the required role" whenever I want to access an [role:admin] protected route.
public function registration(Request $request)
{
...........
$user = User::create($data);
$user->assignRole('admin');
$response = [];
$response['token'] = $user->createToken('api-application')->accessToken;
$response['user'] = [$user, $organization];
return response()->json($response, 202);
}
This is my user model
.......
protected $guard_name = 'api';
protected $table = 'users';
protected $fillable = [
'firstname',
'lastname',
'email',
'password',
'organization_id',
];
In my Controller VisitorsController I added the spatie role middleware to protect like this
public function __construct()
{
$this->middleware(['role:admin']);
}
public function index()
{
$visitor = Visitor::all();
return VisitorsResource::collection($visitor);
}
And in my api.php I have this
Route::middleware('auth:api')->prefix('V1')->group(function () {
........
Route::apiResource('/visitors', VisitorsController::class);
});
.........
Route::post('/register', [AuthController::class, 'registration'])->name('registration');
Have I provided enough information? And please what I'm I doing wrong?
