@babel/plugin-proposal-object-rest-spread not being detected at beta.46

See original GitHub issue

Babel/Babylon Configuration (.babelrc, package.json, cli command)

.babelrc

{
  "presets": [
    ["@babel/env", {
      "targets": { "node": "6.11.5" }
    }]
  ],
  "plugins": ["@babel/plugin-proposal-object-rest-spread"]
}

CLI Command

babel 'functions/src' --out-dir 'functions/bundle' --copy-files --ignore 'functions/src/node_modules'

Expected Behavior

Files are correctly built, as it did with beta.44

Current Behavior

With beta.46, following error arises:

Error: SyntaxError: functions/src/common/getLocations.js: Support for the experimental syntax 'objectRestSpread' isn't currently enabled (77:19):

  75 |         if (key === 'viewport'){
  76 |           const { northeast, southwest } = geometry.viewport;
> 77 |           return {...prev, bounds : {
     |                   ^
  78 |             ne : {
  79 |               lat : northeast.lat,
  80 |               lng : northeast.lng

Add @babel/plugin-proposal-object-rest-spread (https://git.io/vb4Ss) to the 'plugins' section of your Babel config to enable transformation.

Mmm i can´t get it work. What i made:

Rename functions/src/.babelrcto functions/src/babel.config.js
Add the module.exports to this file, resulting:

module.exports = {
  "presets": [
    ["@babel/env", {
      "targets": { "node": "6.11.5" }
    }]
  ],
  "plugins": ["@babel/plugin-proposal-object-rest-spread"]
}

Am I doing something wrong?
