Later you can check DLQ to debug your application and find the reason for failure.ĭon’t want to miss any posts from us? join us on our Facebook group, and follow us on Facebook, Twitter, LinkedIn, and Instagram. ![]() AWS allows us to configure a dead letter queue to handle these failed messages. The SQS dead letter queue comes to the rescue exactly in this case. Well, to keep the flow of the queue normal, it’s a good idea to store those messages somewhere for later debugging. This will result in an infinite loop of trying and re-trying and re-trying … Now, suppose one of the messages is corrupted and despite multiple tries, your application is not able to process it. After the successful processing, you delete the message from the queue. In the preceding example, we can determine, based on the error code, and the error message, that the target queue we specified for the schedule does not exist.Your application is consuming messages from the SQS queue and processing them. You configured on the schedule and is still failing to deliver. The attribute can contain the values MaximumRetryAttempts if EventBridge Scheduler sent it to theĭLQ after it exceeded the maximum retry attempts you configured for the schedule, or MaximumEventAgeInSeconds, if the event is older than the maximum age The target API is a retryable error, and not a permanent error. This attribute will be present if the error from TARGET_ARN – The ARN of the target that your schedule invokes, in the following service ARN format:Īrn:aws:scheduler:::aws-sdk: service: apiAction.ĮXHAUSTED_RETRY_CONDITION – Indicates why the event was delivered to the DLQ. See the following error message instead: Unexpected error occurred while processing the request. If the schedule fails due to an issue with EventBridge Scheduler, you'll The error message returned by Amazon SQS is The specified queue does not exist for this wsdl version. See the following error code instead: .ĮRROR_MESSAGE – Contains the error message that EventBridge Scheduler receives from the target's service API. If the schedule fails to invoke a target due to an issue with EventBridge Scheduler, you'll The error code returned by Amazon SQS is. Note the following attributes in the dead-letter event to help you identify and troubleshoot possible reasons why target inovcation has failed.ĮRROR_CODE – Contains the error code that EventBridge Scheduler receives from the target's service API. ![]() "StringValue": "arn:aws:scheduler:::aws-sdk:sqs:sendMessage", "StringValue": "MaximumEventAgeInSeconds", ![]() "StringValue": "The specified queue does not exist for this wsdl version.", "ReceiptHandle": "AQEBkNKTdOMrWgHKPoITRBwrPoK3eCSZIcZwVqCY0BZ+FfTcORFpopJbtCqj36VbBTlHreM8+qM/m5jcwqSlAlGmIJO/hYmMgn/+dwIty9izE7HnpvRhhEyHxbeTZ5V05RbeasYaBdNyi9WLcnAHviDh6MebLXXNWoFyYNsxdwJuG0f/w3htX6r3dxpXvvFNPGoQb8ihY37+u0gtsbuIwhLtUSmE8rbldEEwiUfi3IJ1zEZpUS77n/k1GWrMrnYg0Gx/BuaLzOrFi2F738XI/Hnh45uv3ca6OYwS1ojPQ1LtX2URg1haV5884FYlaRvY8jRlpCZabTkYRTZKSXG5KNgYZnHpmsspii6JNkjitYVFKPo0H91w5zkHlSx3REAuWk7m3r7PmOMvTNPMhctbD3CkTw=", If successful, you will see output similar to the following. $ aws sqs receive-message -queue-url your-dlq-url -attribute-names All -message-attribute-names All -max-number-of-messages 1
