Github CI/CD pipeline crashes with webpack

Question

I'm trying to learn how CI/CD pipelines work.

I decided to use it with my portfolio page which should re-run itself on every push.

Here is my yaml config:

name: Build Bundle for Github Pages
on:
  push:
    branches:
      - source

env:
  NODE_ENV: production
  PUBLIC_URL: http://crrmacarse.github.io/
  GA_TRACKING_CODE: ${{ secrets.GA_TRACKING_CODE }}
  FIREBASE_TOKEN: ${{ secrets.FIREBASE_TOKEN }}

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout
      uses: actions/checkout@v1
      with:
        persist-credentials: false

    - name: Build
      run: |
        npm install
        npm run prod:pipeline
        npm run sitemap
        cp dist/index.html dist/404.html
        cp google21029c74dc702d92.html dist/
        cp robots.txt dist/

    - name: Deploy
      uses: JamesIves/github-pages-deploy-action@releases/v3
      with:
        ACCESS_TOKEN: ${{ secrets.ACCESS_TOKEN }}
        BRANCH: source
        FOLDER: dist

Here is the error:

If the error message is cannot find module 'html-webpack-plugin', you could try, for testing, to install it.
See survivejs/webpack-book issue 100 as an example:

The solution was to run npm i html-webpack-plugin --save-dev before building with webpack

The OP has fixed the GitHub Action workflow with crrmacarse/crrmacarse.github.io commit 8a4397b

jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/[email protected]

    - name: Use node 12
      uses: actions/setup-node@v1
      with:
          node-version: 12
          registry-url: https://registry.npmjs.org

    - name: install
      run: npm install
    - name: lint
      run: npm run sitemap
    - name: build
      run: npm run prod
    - name: copy
      run: npm run copy

Then the module html-webpack-plugin is properly installed and available, as seen in this Actions CI run.
