did someone encounter this problem when trying to configure the welcome notification using Spatie
I don’t have any WelcomeNotification Model. do i need to make one?
>Solution :
I suppose you have created a notification in the model folder because you are using $user->notify(new WelcomeNotification($validUntil)). And, you are passing WelcomeNotification model into notify as a parameter instead of a notification class object, which causes error.
You need to create the notification in the app/Notifications. So, when you run this command it will automatically create the WelcomeNotification in the app/Notifications folder.
php artisan make:notification WelcomeNotification
Now, import use App\Notifications\WelcomeNotification; in the User model.
