usage error

[ligi]

I am using the action with a simple config like this:

name: prettier review
on: [pull_request]
jobs:
  prettier:
    name: runner / prettier
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: EPMatt/reviewdog-action-prettier@v1
        with:
          github_token: ${{ secrets.github_token }}
          reporter: github-pr-review
          level: error
          prettier_flags: '_data/*/*.json'

but the action fails like this:
