Failed executions in scheduled runs

[fviolette]

When running vale in a cron job, the execution fails. My example includes a custom runner which works in other contexts (push, pr).

on:
  schedule:
    - cron: "0 0 * * 1-5"

jobs:
  deploy:
    runs-on: ["nodejs-16"]
    steps:
    - name: Checkout
      uses: actions/checkout@master
    - name: Vale
      uses: errata-ai/vale-action@reviewdog
      with:
        reporter: github-check
      env:
        GITHUB_TOKEN: ${{secrets.GITHUB_TOKEN}}
