      # Need to cycle through all Lambda functions in the `sam/api` folder and do pip install for all of them respectively.
      # `sam build` does not install the `requirements.txt` for nested Lambda functions so
      # we need to manually install them in the pre-build phase and SAM will package each folder up respectively
      # with the dependencies inside the folders. See your thread about this on the AWS Developers Slack
