BUG REPORT: EventBridge Scheduler does not allow FIFO Dead Letter Queues


I believe I found a defect in the new EventBridge Scheduler product:

  1. FIFO SQS queues require FIFO deal letter queues (https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-dead-letter-queues.html )

  2. When attempting to create a Schedule that targets a FIFO SQS queue, if you specify a FIFO dead letter queue, then the request fails because the regex used to validate the DLQ ARN does not allow for a ".fifo" suffix.

Currently, EventBridge Scheduler does not support using a FIFO queue as your schedule's DLQ.

  • It would be nice if the documentation explicitly stated that "DLQs are supported by Scheduler if your target is a FIFO SQS Queue."

    Would also be nice to know if this is a feature being pursued or if this is the permanent state of this product.


Hi, AWS service teams usually do not monitor re:Post re. bugs. To get yours fixed, you have to open a Support ticket via the AWS console of your account. Best, Didier
