I have a website which is hosted on GitHub; I use hugo v0.83.0 and the PaperMod theme. Everything used to work without any issues until recently, but today I pushed some minor changes and got the following error message from GitHub actions:

I have configured GitHub actions using this YAML file, that is,

name: Deploy Hugo PaperMod Demo to Pages

  push:
    paths-ignore:
      - "images/**"
      - "LICENSE"

  workflow_dispatch:

    needs: build
    steps:
      - name: Deploy to GitHub Pages
        id: deployment
        uses: actions/deploy-pages@v1

I would appreciate any help with this.

You need to upgrade Hugo to a later version.
