Trouble importing to esbuild.config.js from an internal monorepo package

[bryansoftdev]

Describe the bug
I'm trying to import some of the config from a pnpm workspace internal package. But the import doesn't seem to be resolving correctly in the config file. It resolves fine in my app's index.ts file.

To Reproduce

1. Use config option in ./apps/service/serverless.yml

  custom:
    esbuild:
      config: './esbuild.config.js'

2. Export something in /packages/sentry-wrapper/index.ts

const sentryConfig = {
  sourcemaps: true,
  plugins: [ sentryEsbuildPlugin({
    ...
  })],
};

export default {
  sentryConfig
};

3. Try to import it in ./apps/service/esbuild.config.js

const { sentryConfig } = require('sentry-wrapper');

module.exports = () => ({
  ...sentryConfig,
  exclude: ['@aws-sdk'],
  watch: {
    pattern: ['./**/*.(js|ts)', '../../packages/**/*.ts'],
  },
});

4. Run serverless deploy Cannot find module 'sentry-wrapper'

Expected behavior
Should be able to import from internal packages.

Versions (please complete the following information):

• OS: Mac
• "serverless": "^3.35.2"
• "serverless-esbuild": "^1.48.4"

Thanks for any help. (Any ideas on other ways I can get this working?)

I figured it out. Now using CommonJS for exports instead of ESM.
