Issue of the label configuration file ".github/labeler.yml"

Associated GitHub Community ticket: https://github.community/t/labeler-typeerror-glob-pattern-string-required/133467

According to the README of this action, the following configurations in the label configuration file should work:

label-1:
  - any: ['list', 'of', 'globs']
    all: ['list', 'of', 'globs']

label-2:
  - example1/*
  - example2/**/*

I tested with two label configuration files in my repository (see here).

• .github/labeler-01.yml

  common:
    - any: ['./*', './src/**']
  
  workflow:
    - any: ['.github/workflows/**']
  

• .github/labeler-02.yml

  repo:
    - './*'
    - './src/**'
  
  GHA:
    - '.github/**'
  

And my workflow looks like this (see here):

name: CI

on: pull_request

jobs:
  job1:
    runs-on: ubuntu-latest
    steps:         
      - name: PR Labeler
        uses: actions/labeler@2.2.0
        with:
          repo-token: ${{ secrets.GITHUB_TOKEN }}
          configuration-path: .github/labeler-01.yml

  job2:
    runs-on: ubuntu-latest
    steps:         
      - name: PR Labeler
        uses: actions/labeler@2.2.0
        with:
          repo-token: ${{ secrets.GITHUB_TOKEN }}
          configuration-path: .github/labeler-02.yml

I changed the following files:

• ./.github/workflows/ci.yml
• ./test.txt
• ./src/test.txt

However, finally only the GHA label was added successfully, the other three should also be added but not (see the example PR).

When using ‘.github/labeler-01.yml’, the actions always fails with the error (see job1):

##[error]TypeError: glob pattern string required
##[error]glob pattern string required

When using ‘.github/labeler-02.yml’, the action displays as success, but only the GHA label is added (see job2).

Ok, I have found what is the culprit there. The meaning of any and all is poorly defined. The issue there is that

- any: ['./*', './src/*']

and

- ./*
- ./src/*

Have different meaning. The list in any mean that any file in the PR must match all globs in the list. With all it mean that all files in the PR must match all globs in the list. So to have the same behaviour with any you need to use:

- any: ['./*']
- any: ['./src/*']

Hit this error just now:

• https://github.com/OpenISS/OpenISS/blob/master/.github/labeler.yml
• https://github.com/OpenISS/OpenISS/pull/86
• https://github.com/OpenISS/OpenISS/runs/4811417470

It appears to have labeled two things correctly before barfing out.
