Sqs lambda doesn't work for FIFO queue

[mmuller88]

The aws-sqs-lambda pattern fails if you want to use a fifo sqs queue as the documentation says that the name of the queue needs to end with .fifo https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queues.html . But as the dead letter queue is applied too and gets the same name when you use the queueProps parameter. https://github.com/awslabs/aws-solutions-constructs/blob/master/source/patterns/%40aws-solutions-constructs/aws-sqs-lambda/lib/index.ts#L51

One easy fix would be to create dlqueueProps . I created a PR: #13

Reproduction Steps

Apply:

    const sqsToLambda = new SqsToLambda(scope, 'SqsToLambda', {
      deployLambda: false,
      existingLambdaObj: this.executerLambda,
      queueProps: {
        queueName: `${scope.stackName}.fifo`,
        fifo: true,
      },
    });

Environment

• **CDK CLI Version : 1.47
• **AWS Solutions Constructs Version : 1.47

Other

My current workaround is to disable the deadletter queue with

deployDeadLetterQueue: false
