HttpError: Not Found when run with new yml config

[flexzuu]

I tried to use the labeler with the new YML syntax and it seems there is an issue on how the labeler is published. I always get the following msg.
I tested the v2 and v2.0.0 releases

Run actions/labeler@v2.0.0
  with:
    repo-token: ***

I also face the same issue. Here is the workflow where labeler fails:

name: Foo workflow
on:
  pull_request:
    branches:
      - master
    paths:
      - environments/dev/*
      - modules/*
jobs:
  pr_labeler:
    name: PR Labeler
    runs-on: ubuntu-18.04
    steps:
      - name: Set PR label
        if: github.event.action == 'opened' || github.event.action == 'synchronize'
        uses: actions/labeler@v2.0.0
        with:
          repo-token: ${{ secrets.GITHUB_TOKEN }}

Bellow are the job logs:

Getting the same issue (on a private repo):

.github/workflows/labeler.yml

name: Labeler
on: [pull_request]
jobs:
  label:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/labeler@v2
      with:
        repo-token: "${{ secrets.GITHUB_TOKEN }}"

.github/labeler.yml

logan:
  - packages/logan/*

main:
  - packages/main/*

eavis:
  - packages/eavis/*

shared:
  - packages/shared/*

xavier:
  - packages/xavier/*

gambit:
  - packages/gambit/*

It does resolve to actions/labeler@master, but fails afterwards as lib is not present there

I'm encountering this issue too; I've validated the yml file, and we're using the default configuration provided by labeler.

I also continue to get this issue using the default configuration

name: Labeler
on: [pull_request]

jobs:
  label:

    runs-on: ubuntu-latest

    steps:
    - uses: actions/labeler@v2
      with:
        repo-token: "${{ secrets.GITHUB_TOKEN }}"

Check the usage here - https://github.com/actions/labeler#usage. Basically, you need to have the file .github/labeler.yml

My issue was that I wrote .github/labeler.yaml instead of .github/labeler.yml (be careful with that)
