External node module not being packed

Serverless Framework
,
1

Hi all!

I’m trying to deploy some functions that use Ramda but for some reason that package is not being bundled in the .serverless folder. It reports that it is bundling the module but somehow it just never gets into the .zip file. There are no reported errors or anything that would lead me to believe that it couldn’t find it. I thought it was ok until I saw the error log in AWS. I saw External Npm modules cannot be referenced v1.0(Bug) but that seems to have been user error (which hopefully this is as well).

Relevant output from sls deploy --noDeploy

$ SLS_DEBUG=* sls deploy "--noDeploy"

error Command failed with exit code 1.

I don’t think the error at the end is related to this issue. I brought it up in another topic

package.json inside .zip file

{
  "dependencies": {
    "@google-cloud/language": "^0.10.6",
    "auth0": "^2.7.0",
    "bluebird": "^3.5.0",
    "http-status": "^1.0.1",
    "ramda": "^0.24.1",
    "uuid": "^3.1.0",
    "watson-developer-cloud": "^2.33.0"
  }
}

webpack.config.js

const nodeExternals = require('webpack-node-externals');

module.exports = {
  entry: './src/handlers.js',
  externals: [nodeExternals()],
  module: {
    loaders: [
      {
        exclude: /node_modules/,
        loaders: ['babel-loader'],
        test: /\.jsx?$/,
      },
    ],
  },
  output: {
    filename: 'handlers',
    libraryTarget: 'commonjs',
    path: '.webpack/src',
  },
  target: 'node',
};

.babelrc

{
  "presets": [
    "es2015",
    "flow",
    "stage-2"
  ],
  "plugins": [
    [
      "transform-builtin-extend",
      {
        "globals": ["Error"]
      }
    ],
    "ramda",
    "add-module-exports",
    "transform-decorators-legacy"
  ]
}

*Note that removing the "ramda" plugin from babel does not fix the issue.

(partial) serverless.yml

custom:
  webpackIncludeModules:
    packagePath: './package.json'

Turns out this is a bug in NodeJS v8.1 (https://github.com/nodejs/node/issues/12921) Downgrading my deploy environment to 6.10 fixes the issue
