I have a project based on an AWS Quick Start solution ([login to view URL]). I have had the project converted from running on EC2 to Lambda. It was working and tested in us-east-1 so functionally it works. I have moved it to us-west-2 but there is something wrong. I suspect it is the configuration with Cognito as I now can't create a User.
I need the issues fixed and a serverless script updated to make sure all the dependencies are configured correctly. I will give you access to AWS and the project. It can be tested through the web client provided in the Github project above.
