        Description copied from interface: AuditEventHandler
        Publishes an event to the provided topic.

        Note for implementors, it is imperative that the supplied event is not modified in any way as this may cause undesirable behaviour where multiple handlers are configured. If the event must be modified, then make a copy of it and work with that.

        publishEvent in interface AuditEventHandler
        Parameters:
        context - The context chain that initiated the event.
        topic - The topic where to publish the event.
        event - The event to publish - which should be considered immutable.
        Returns:
        a promise with either a response or an exception
