AWS Lambda - How to stop retries when there is a failure

Question

I know that when a Lambda function fails (for example when there is a time out), it tries to run the function 3 more times again. Is there any way to avoid this behavior? I\

Use below code to identify and stop retry when there is a failure.

  exports.handler = (event, context, callback) => {
      context.callbackWaitsForEmptyEventLoop = false;
      let lastReqId;
      if (lastReqId == context.awsRequestId) {
        console.log("Lambda auto retry detected. Aborting");// you can write your own logic to decide what to do with the failure data
        return context.succeed();
      } else {
        console.log("new context");
        lastReqId = context.awsRequestId;
      }
    };
