Error: No authentication information found

Describe the bug

Hello,

I am facing the following error using GitHub Copilot CLI programatically:

Error: No authentication information found.
Copilot can be authenticated with GitHub using an OAuth Token or a Fine-Grained Personal Access Token.
To authenticate, you can use any of the following methods:
  • Start 'copilot' and run the '/login' command
  • Set the COPILOT_GITHUB_TOKEN, GH_TOKEN, or GITHUB_TOKEN environment variable
  • Run 'gh auth login' to authenticate with the GitHub CLI
Error: Process completed with exit code 1.

Here is how the Actions workflow is configured:

name: Test GitHub Copilot CLI

on:
  workflow_dispatch:
      node_version:
        description: Node.js Version
        required: false
        default: '24.x'
        type: string

permissions:
  contents: read

jobs:
  copilot_cli_test:
    name: Send test message
    runs-on: ubuntu-latest
    steps:
      - name: Setup Node.js
        uses: actions/setup-node@v6
        with:
          node-version: ${{ inputs.node_version }}

      - name: Install Copilot CLI
        run: npm install -g @github/copilot

      - name: Run Copilot CLI
        env:
          GITHUB_TOKEN: ${{ secrets.PERSONAL_ACCESS_TOKEN }}
        run: |
          copilot -p "Review the git log for this repository and write a bullet point summary of all code changes that were made today, with links to the relevant commit on GitHub. Above the bullet list give a description (max 100 words) summarizing the changes made. Write the details to summary.md" --allow-tool='shell(git:*)' --allow-tool=write --no-ask-user
          cat summary.md >> "$GITHUB_STEP_SUMMARY"

The environment variable COPILOT_GITHUB_TOKEN was also considered on the test, that returns the same error.

Follow below the fine grained token created for the workflow:

Affected version

GitHub Copilot CLI 1.0.61.

Steps to reproduce the behavior

The GitHub Action workflow is running in a repository that belongs to an organization.

1. Set the GitHub Action workflow secret in repository settings
2. Prepare the workflow file
3. Start workflow manually

Any feedback is highly appreciated.
