send_error is never triggered

The sns_alert is not used anywhere.

Hi @gocho1 you're right sns_alert is a leftover from the initial dev phase.
to handle in a proper way the Lambda Error you need to change the serverless.yml config adding the following yaml key

onError: arn:aws:sns:us-east-1:XXXXXX:sns-topic # Optional SNS topic
Official Doc

or in Terraform using dead_letter_config as described in the Terraform Docs

This feature is not enabled by default in the repo due to the lambda error handling is not part of the main scope of this repo.
Different team prefer to handle the lambda error in many different ways, I will remove the leftover python code asap.
