Lack of understanding, I think every new dev to serverless will have this stage of frustration, then eventually will find a way to do better with creative ideas, I myself never run lambda in the cloud I write a UT for my handler and assume I know the input and the expected output, I mock everything except step functions I use the official jar from AWS.
