A company has an application that processes information from documents that users upload. When a user uploads a new document to an Amazon S3 bucket, an AWS Lambda function is invoked and processes the document.

Explanation
Using an SQS queue to capture failed document processing ensures that all documents, including those that fail due to formatting errors, are eventually processed. By invoking a Step Functions workflow from a second Lambda function, errors can be handled, retried, or logged without blocking the processing of other documents, ensuring timely and reliable processing with minimal operational overhead.
