[zeshuaro]

Describe the bug

When using the token generated by actions/create-github-app-token and provided as the token parameter, the action fails with the following error:

Run FantasticFiasco/[email protected]
  with:
    token: ***
    commitTitle: docs(license): update copyright year to {{ currentYear }}
    prTitle: docs(license): update copyright year to {{ currentYear }}
    labels: documentation

To Reproduce

Use the following workflow with a GitHub app details:

jobs:
  update-license:
    name: Update license year
    runs-on: ubuntu-latest

    steps:
      - name: Create GitHub App token 🔑
        id: app-token
        uses: actions/create-github-app-token@v1
        with:
          app-id: ${{ secrets.GH_APP_ID }}
          private-key: ${{ secrets.GH_APP_PRIVATE_KEY }}

      - name: Checkout 🛎️
        uses: actions/checkout@v4
        with:
          fetch-depth: 0
          token: ${{ steps.app-token.outputs.token }}
          persist-credentials: false

      - name: Update license year 🪪
        uses: FantasticFiasco/[email protected]
        with:
          token: ${{ steps.app-token.outputs.token }}
          commitTitle: "docs(license): update copyright year to {{ currentYear }}"
          prTitle: "docs(license): update copyright year to {{ currentYear }}"
          labels: documentation

Expected behavior

The workflow should work with a GitHub app token

Hi there and welcome to this repository!

A maintainer will be with you shortly, but first and foremost I would like to thank you for taking the time to report this issue. Quality is of the highest priority for us, and we would never release anything with known defects. We aim to do our best but unfortunately you are here because you encountered something we didn't expect. Lets see if we can figure out what went wrong and provide a remedy for it.

Hi @zeshuaro and thanks for reporting the issue!

I've added this issue to my list of things to do, but cant unfortunately start working on it right now. In order for this to be efficient, and since the environment to reproduce this is challenging, could you please provide complete instructions on how to setup the environment, please bear in mind that I don't have a GitHub app. A quick glance tells me that the workflow exists in an external repo, would that be a factor in this issue or can this be reproduced in one repository?

[zeshuaro]

You can follow the GitHub docs to create an app of your own. Once you have created the app, you can obtain its app ID and secret which can then be specified to the example workflow I shared above to reproduce the problem in any repository.
