Upload source maps to Honeybadger

[ras1]

If you want to upload the source maps from the gh-pages branch, you would need to check out the gh-pages branch after deploying and then upload the source maps. Here’s an updated version of the workflow to achieve that:
name: Deploy to GitHub Pages

on:
push:
branches:
- main

jobs:
build-and-deploy:
runs-on: ubuntu-latest

steps:
  - name: Checkout repository
    uses: actions/checkout@v2

  - name: Set up Node.js
    uses: actions/setup-node@v2
    with:
      node-version: '14'

  - name: Install dependencies
    run: npm install

  - name: Build the project
    run: npm run build

  - name: Deploy to GitHub Pages
    run: |
      npm install -g gh-pages
      gh-pages -d build

  - name: Checkout gh-pages branch
    run: |
      git fetch origin gh-pages:gh-pages
      git checkout gh-pages

  - name: Upload Source Maps to Honeybadger
    env:
      HONEYBADGER_API_KEY: ${{ secrets.HONEYBADGER_API_KEY }}
      REVISION: ${{ github.sha }}
    run: |
      for file in static/js/*.map; do
        curl https://api.honeybadger.io/v1/source_maps \
          -F api_key=$HONEYBADGER_API_KEY \
          -F revision=$REVISION \
          -F minified_url=https://<YOUR_GITHUB_USERNAME>.github.io/<YOUR_REPO_NAME>/static/js/$(basename ${file%.map}) \
          -F source_map=@$file \
          -F minified_file=@${file%.map}
      done

This updated workflow checks out the gh-pages branch after deploying and then uploads the source maps from that branch.
