What happens to enqueue, dequeue, or propagation if the transformation mapping raises an error?
Enqueue and dequeue of the message will raise the error to the application. If the error occurs during the dequeue operation, the retry count of the message is incremented. If the retry count exceeds max_retries, the message is moved to the exception queue. If the error occurs during propagation, it is handled in a manner similar to dequeue; propagation of the message will fail. It will be attempted again and the message will be moved to the exception queue when retry count exceeds max_retries for the queue.
