A developer has an application container, an AWS Lambda function, and an Amazon Simple Queue Service (Amazon SQS) queue. The Lambda function uses the SQS queue as an event source. The Lambda function makes a call to a third-party machine learning API when the function is invoked. The response from the third-party API can take up to 60 seconds to return. The Lambda function’s timeout value is currently 65 seconds. The developer has noticed that the Lambda function sometimes processes duplicate messages from the SQS queue. What should the developer do to ensure that the Lambda function does not process duplicate messages?
