When I try to create a lambda function with a local code path, like:

const helloWorldFn = new lambda.Function('hello-world', {
  code: new asset.FileArchive(`${__dirname}/../../build`),
  handler: 'build/src/index.telemetryClassifierHandler',
  name: 'pulumiTestFn',
  publish: true,
  role: role.arn,
  runtime: 'nodejs14.x',
  tracingConfig: {
    mode: 'ACTIVE',
  },
});

I am seeing a

ValidationError

like in the attached image, however I can upload a zip file of that directory in the AWS console (or via serverless and/or terraform) and all of them seem to be okay with the contents of the

build

dir. I have tried creating a zip file separately and using that file as the

FileArchive

, as well as changing the handler to include the

build/

prefix or not I don't see any useful logs on what is failing to validate when using

--debug

or

--verbose 4

. Has anyone seen this before, or know how to debug what is wrong?
