AWS SQS AWS.SimpleQueueService.InvalidMaximumMessageSize

What is AWS SQS AWS.SimpleQueueService.InvalidMaximumMessageSize

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.InvalidMaximumMessageSize. This error typically occurs when there is an issue with the message size configuration in your SQS queue.

What You Observe

Developers may notice that messages are not being sent to the queue, and the AWS Management Console or SDKs return an error indicating an invalid maximum message size.

Explaining the Issue

The error code AWS.SimpleQueueService.InvalidMaximumMessageSize indicates that the maximum message size set for the queue is outside the allowable range. AWS SQS supports message sizes from 1 KB (1024 bytes) to 256 KB (262144 bytes). If your configuration exceeds these limits, the error is triggered.

Why This Happens

This issue often arises when there is a misconfiguration during the queue setup or when attempting to change the queue's attributes without adhering to the allowed size constraints.

Steps to Fix the Issue

To resolve this error, you need to ensure that the maximum message size is set within the valid range. Follow these steps to adjust the configuration:

Using AWS Management Console

Navigate to the AWS SQS Console. Select the queue you want to configure. Choose Queue Actions and then Edit Queue Attributes. In the Maximum Message Size field, enter a value between 1024 and 262144 bytes. Save the changes.

Using AWS CLI

Open your terminal or command prompt. Run the following command to set the maximum message size: aws sqs set-queue-attributes --queue-url --attributes MaximumMessageSize= Replace <your-queue-url> with your actual queue URL and <desired-size-in-bytes> with a valid size.
