Help deploying Functions to Serverless AWS

I’m using the yarn rw deploy serverless to deploy directly to AWS. I’m having trouble with the auto-generated lambda functions not importing modules correctly. A simple example is a ‘hello’ Function with and without import { logger } from 'src/lib/logger'.

import type { APIGatewayEvent, Context } from 'aws-lambda'
import { logger } from 'src/lib/logger'
export const handler = async (event: APIGatewayEvent, context: Context) => {
  logger.info('Invoked hello function')

  return {
    statusCode: 200,
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      data: 'hello function',
    }),
  }
}

crashes with the error stack in CloudWatch of:

{
    "errorType": "Runtime.ImportModuleError",
    "errorMessage": "Error: Cannot find module '..\\..\\lib\\logger'\nRequire stack:\n- /var/task/api/dist/functions/hello/hello.js\n- /var/task/hello.js\n- /var/runtime/UserFunction.js\n- /var/runtime/Runtime.js\n- /var/runtime/index.js",
    "stack": [

        "Require stack:",

        "- /var/task/hello.js",
        "- /var/runtime/UserFunction.js",
        "- /var/runtime/Runtime.js",
        "- /var/runtime/index.js",
        "    at _loadUserApp (/var/runtime/UserFunction.js:221:13)",

        "    at Object.<anonymous> (/var/runtime/index.js:43:34)",
        "    at Module._compile (internal/modules/cjs/loader.js:1085:14)",
        "    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1114:10)",
        "    at Module.load (internal/modules/cjs/loader.js:950:32)",
        "    at Function.Module._load (internal/modules/cjs/loader.js:790:12)",

        "    at internal/main/run_main_module.js:17:47"
    ]
}

but removing the logger import and the logger call from the lambda Function, when deployed returns the expected {"data":"hello function"}.

Am I missing a setting or are the zipballs not generating correctly, or?

Thanks!
