AWS SQS AWS.SimpleQueueService.InvalidBatchEntryId error encountered when sending messages in batch.

What is AWS SQS AWS.SimpleQueueService.InvalidBatchEntryId error encountered when sending messages in batch.

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 using AWS SQS to send messages in batch, you might encounter the error code AWS.SimpleQueueService.InvalidBatchEntryId. This error indicates that there is an issue with one or more of the batch entry IDs provided in your request.

Observed Error

The error message typically looks like this:

{ "Error": { "Code": "AWS.SimpleQueueService.InvalidBatchEntryId", "Message": "The batch entry ID is invalid." }}

Details About the Issue

The AWS.SimpleQueueService.InvalidBatchEntryId error occurs when the batch entry ID used in a batch request does not meet the required criteria. Each batch entry ID must be unique within the batch and should only contain alphanumeric characters, hyphens, and underscores. The IDs are used to identify each message in the batch uniquely.

Common Causes

Using non-alphanumeric characters in the batch entry ID. Duplicate batch entry IDs within the same batch request. Exceeding the maximum length for batch entry IDs.

Steps to Fix the Issue

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

Step 1: Validate Batch Entry IDs

Ensure that each batch entry ID is unique within the batch and contains only alphanumeric characters, hyphens, and underscores. For example:

{ "Id": "msg1", "MessageBody": "Hello World"},{ "Id": "msg2", "MessageBody": "Hello Again"}

Step 2: Check for Duplicates

Review your batch request to ensure there are no duplicate IDs. Each ID should be distinct to avoid conflicts.

Step 3: Use Valid Characters

Ensure that your IDs do not contain any special characters other than hyphens and underscores. For example, msg-1_2023 is valid, but msg@1#2023 is not.

Step 4: Test Your Changes

After making the necessary changes, test your batch request to ensure that the error is resolved. You can use the AWS CLI or SDKs to send a test batch request.
