Unable to use built-in GitHub Token for avoiding rate limit issues on GHES

Description:
For our enterprise we are facing "API rate limit exceeded ..." errors. I read the documentation how to avoid rate limit issues but for our enterprise using PAT is not feasible. I would like to use the GITHUB-TOKEN for authentication in my Github Workflow since this is the recommended way from GitHub. However, this is not possible at the moment resulting in a Bad Credentials error.

It seems that the AUTH variable variable is not usable in this case since only personal tokens are authenticated with Authorization: token <TOKEN> but for GITHUB-TOKEN one needs to use Authorization: <GITHUB_TOKEN> instead as can be seen in the workflow below in step read limit.

Action version:
4.6.1

Platform:

  • Ubuntu

Runner type:

  • Self-hosted

Tools version:

All

Repro steps:

On GHES, following this example I used the following workflow:

name: CI With GitHub Token

on: [workflow_dispatch]

jobs:
  sample_build:
    runs-on: [azure-runners]
    steps:
      - name: "rate limit"
        run: |
          curl \
            -H "Accept: application/vnd.github.v3+json" \
            -H "Authorization: $TOKEN" \
            https://api.github.com/rate_limit
        env:
          TOKEN: ${{ secrets.GITHUB_TOKEN }}

      - name: Clear the tool cache
        run: rm -rf /Users/runner/hostedtoolcache/Python/

      - name: Set up Python
        uses: actions/setup-python@v4.6.1
        with:
          token: ${{ secrets.GITHUB_TOKEN }}
          python-version: 3.9.12

      - name: "rate limit"
        run: |
          curl \
            -H "Accept: application/vnd.github.v3+json" \
            -H "Authorization: $TOKEN" \
            https://api.github.com/rate_limit
        env:
          TOKEN: ${{ secrets.GITHUB_TOKEN }}

Expected behavior:
Installation of python version 3.9.12 and drop of rate limits from 60 to 58.

Actual behavior:
Failure with error Bad Credentials.
