found unexpected type for label 'xxxxxxxx' (should be array of config options)

[danielmayor]

Description:
Somehow, today the labeler action started to fail. I didn't change any labeler config file or setup. I wonder if it's because of the new release (v5.0.0).

Execution output:

Run actions/labeler@master
  with:
    repo-token: ***
    configuration-path: .github/labeler.yml
    sync-labels: false
    dot: true
The configuration file (path: .github/labeler.yml) was not found locally, fetching via the api
Error: Error: found unexpected type for label 'frontend' (should be array of config options)
Error: found unexpected type for label 'frontend' (should be array of config options)

.github/labeler.yml:

frontend:
  - shared/frontend/**/*

pdf:
  - shared/pdf/**/*

configurations:
  - .circleci/**/*
  - .github/**/*

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Repro steps:
The action runs automatically every time I create a PR. The labeler.yml hasn't any changes.

Expected behavior:
Action should run successfully.

Actual behavior:
I get this error: Error: Error: found unexpected type for label 'frontend' (should be array of config options)

Hello @danielmayor!
Thank you for creating the issue!

Yes, you are right, this failure is related to the new major release. You are using the main branch that contains the latest changes. According to the GitHub Actions documentation, it is not recommended to pin workflow to the main branch, because it can include breaking changes.

To mitigate the issue, please read the action documentation to find out how to adapt your configuration files for use with the new action version or use v4 tag that contains the previous version of configuration file structure.

I would tend to say that the documentation is not correct. I'm running into the same problem mentioned in the description, having the following labeler configuration (please note that I tried different variations)

terraform:
  - changed-files:
    - any-glob-to-any-file: terraform/**

Which to me looks similar to the following snippet from the documentation mentioned above

Documentation:
- changed-files:
  - any-glob-to-any-file: docs/*

The workflow definition is also similar to what I've seen in the documentation

Am I missing something?
