update-ns-webpack, error updating webpack config

[funder7]

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 6.8.0

• Plugin(s): nativescript-stripe

• Node.js: v12.18.3

• Please, attach your package.json and webpack.config.js as these configurations are usually critical for investigating issues with webpack

• package.json: https://pastebin.pl/view/13670ec9

• webpack.config.js: https://pastebin.pl/view/4b6a757b

Describe the bug

Error showing after launching ./node_modules/.bin/update-ns-webpack --configs:

internal/modules/cjs/loader.js:968
  throw err;
  ^

Error: Cannot find module '../projectHelpers'

To Reproduce
I was updating an old project (a plugin), after running npm install i received a notice:

Note: webpack.config.js is different than the suggested @nativescript/webpack config at ..project_dir/node_modules/@nativescript/webpack/templates/webpack.angular.js.
If you have build trouble you can update to latest config using "./node_modules/.bin/update-ns-webpack --configs" command.

Running the suggested command is throwing the error.

Expected behavior

• the update command should be updated to the latest version
• it should update your webpack configuration without any errors

Additional context
I was going to open a PR to fix this, unfortunately the github repo doesn't seem to be aligned with the latest npm release (2.1.3), the most updated branch (feat/webpack-updates) is at 2.0.0-alpha.3 ... Please, if possible keep repo's tags aligned in order to let people contribute ;)

** Fix **

const {
    getPackageJson,
    getProjectDir,
    writePackageJson,
} = require("../projectHelpers");

Replace with:

const {
    getPackageJson,
    getProjectDir,
    writePackageJson,
} = require("../helpers/projectHelpers");
