Cannot get it to add any labels

[AndrewLeedham]

I don't seem to be able to get this action to add any labels.
Using the following workflow:

on:
  pull_request:
    types: [opened]
name: Add base branch label
jobs:
  base-branch:
    runs-on: ubuntu-latest
    steps:
      - name: Add base branch label
        uses: ffittschen/pr-branch-labeler@v1
        with:
          repo-token: ${{ secrets.GITHUB_TOKEN }}

and the following pr-branch-labeler.yml

development:
  base: 'development'

stage:
  base: 'stage'

master:
  base: 'master'

The workflow is running, but there is no output (tested with both draft and normal PR) base branch was "development".

Unfortunately I am trying this in a private repo, otherwise I would share a link, but here are some screenshots:

Hi @AndrewLeedham, is the pr-branch-labeler.yml file already present in your repo or did you add it in the PR that also adds the workflow?

It is part of the PR, guessing the action cannot access it in that case then?

Yes exactly, the action uses the octokit.repos.getContents() method without passing the ref, so it will look for the file in the default branch of the repository.

Gotcha, thanks for the fast response!
