My Setup
I have a typescript CDK Project which deploys several lambdas to AWS using a CDK pipeline.
I am using aws-cdk-local and localstack to run some tests in a codebuild action in a CDK pipeline. I want to do this so I can create a local dynamodb stack to run my tests against in the pipeline (before deployment of the real stack).
My Problem
This works fine on my own PC but I am getting the following error from codebuild when I run cdklocal bootstrap and cdklocal deploy from my codebuild action.
Environment aws://000000000000/ap-southeast-1 failed bootstrapping: Error: Need to perform AWS calls for account 000000000000, but no credentials have been configured.
Here is a screenshot 
You can see I even tried setting mock credentials but it didn't help.
Am I missing something?
Has anyone had success running cdklocal from AWS Codebuild?
Thanks :)
For completeness here is my code
