AWS SQS AWS SQS returns an error indicating that the specified queue does not exist.

The queue URL is incorrect or the queue has not been created in the specified region.

Understanding AWS SQS

Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. SQS eliminates the complexity and overhead associated with managing and operating message-oriented middleware, and empowers developers to focus on differentiating work.

Identifying the Symptom

When working with AWS SQS, you might encounter the error code AWS.SimpleQueueService.QueueDoesNotExist. This error indicates that the queue you are trying to access does not exist in the specified region or the URL is incorrect.

Common Scenarios

  • Attempting to send or receive messages from a queue that has not been created.
  • Using an incorrect queue URL or region in your application configuration.

Understanding the Issue

The error code AWS.SimpleQueueService.QueueDoesNotExist is returned when the AWS SQS service cannot find the specified queue. This could be due to a typo in the queue URL, the queue being deleted, or the queue being created in a different region than expected.

Why This Happens

  • Incorrect Queue URL: The URL used to access the queue might be incorrect. This is a common issue when copying URLs manually.
  • Region Mismatch: AWS SQS queues are region-specific. If you are trying to access a queue in a different region, you will encounter this error.

Steps to Fix the Issue

To resolve the AWS.SimpleQueueService.QueueDoesNotExist error, follow these steps:

Verify the Queue URL

  1. Log in to the AWS Management Console.
  2. Navigate to the SQS service.
  3. Locate the queue you are trying to access and verify that the URL matches the one used in your application.

Check the Region

  1. Ensure that your application is configured to use the correct AWS region where the queue is hosted.
  2. In the AWS Management Console, check the region in the top right corner to ensure it matches the region of your queue.

Create the Queue if Necessary

  1. If the queue does not exist, you can create it by clicking on 'Create Queue' in the SQS console.
  2. Follow the prompts to set up the queue with the desired configurations.
