v4.2.3 - Nested Services - Serverless package at root doesn't work

[bgrand-ch]

Hello, thanks for this amazing plugin!

I would like to use this monorepo structure:

[root]

• common/
  • helper1.js
  • helper2.js
• packages/
  • package1/
    • package.json
    • serverless.yml
    • lambda1.js
    • lambda2.js
  • package2/
    • package.json
    • serverless.yml
    • lambda1.js
    • lambda2.js
• package.json
• serverless.yml
• seed.yml
• .eslintrc.js

...and run yarn build (serverless package script) at the root. Unfortunately, it doesn't work. I have this error message:

yarn run v1.22.10
$ serverless package
Serverless: Cleaning dependency symlinks
Serverless: Creating dependency symlinks
Serverless: Bundling with Webpack...

serverless.yml at root is used to configure serverless plugins.

Is there a way to use the monorepo structure above?

Root package.json content:

{
  "private": true,
  "name": "project-name",
  "version": "1.0.0",
  "scripts": {
    "dev": "serverless offline start --noPrependStageInUrl",
    "build": "serverless package"
  },
  "devDependencies": {
    "eslint-config-standard": "16.0.2",
    "serverless-bundle": "4.2.3",
    "serverless-offline": "6.9.0",
    "serverless-seed": "0.3.13"
  },
  "dependencies": {
    "lambda-log": "2.4.0"
  },
  "license": "MIT"
