I just realized that this file: https://github.com/aws/aws-cdk/blob/main/packages/%40aws-cdk/custom-resource-handlers/test/custom-resources-framework/expected/singleton-function-eval-nodejs.ts is not the real source code, since the real file is being generated.

I don't understand the mechanism that generates that file, nor could I find where I would need to make the change. Thus, this is as far as I can go. I hope someone can pick this up and finish it.
