ContentPublishing Notification triggers twice

Questions
1

Hello everyone,

I’ve noticed that the ContentPublishingNotification in Umbraco is being triggered twice when publishing content. This causes my INotificationHandler<ContentPublishingNotification> to execute twice, which leads to unintended behavior in my logic.

I would like to understand:

  1. Why does ContentPublishingNotification trigger twice during a single publish action?
  2. Is there a way to prevent this behavior so that my NotificationHandler only runs once per publish event?

Here is my current handler implementation:

public class AuditLogCreatedNotificationHandler : INotificationAsyncHandler<ContentPublishingNotification>
{
    public AuditLogCreatedNotificationHandler()
    {

    }

    public async Task HandleAsync(ContentPublishingNotification notification, CancellationToken cancellationToken)
    {
       // business logic
    }
}

Has anyone else experienced this issue? Is there a recommended way to ensure the notification is only triggered once?

Thanks in advance for any insights!
