Getting npm ci && npm run build Error with GitHub Actions (React-Firebase app)

I have the following .yml file:

# This file was auto-generated by the Firebase CLI
# https://github.com/firebase/firebase-tools

name: Deploy to Firebase Hosting on merge
'on':
  push:
    branches:
      - main
jobs:
  build_and_deploy:
    runs-on: ubuntu-latest
    steps:
    
      - uses: actions/checkout@v2
      - run: npm ci && npm run build
      - uses: FirebaseExtended/action-hosting-deploy@v0
        with:
          repoToken: '${{ secrets.GITHUB_TOKEN }}'
          firebaseServiceAccount: '${{ secrets.FIREBASE_SERVICE_ACCOUNT_PROTOTYPE_D7D0D }}'
          channelId: live
          projectId: prototype-d7d0d

As soon as I push to the main branch, the build fails at the statement 'npm ci && npm run build' with the following messages:

Run npm ci && npm run build

I went through other answers/articles that describe similar issues and tried implementing them but no luck so far. Please let me know in the comments if you want me to provide any more details. Any assistance is appreciated, thanks.
