Small recommendtation for your article, the SQS i will recommend to create direcly in the AWS CLI, its can be done very simple
aws sqs create-queue --queue-name your-sqs-name
After that you add triggers, its you can do it with AWS CLI to, you have the output from the SQS creation and you know your function name so its can be done like
aws lambda create-event-source-mapping --function-name {function-name} --event-source-arn {sqs-arn}
Just at recommendation, and a way to simple your process :) happy developering.
