GitHub token is required to authenticate Octokit Unable to fetch previous test results - this is likely a permissions issue. To enable previous results and test metrics, you need to: 1. Set the GITHUB_TOKEN environment variable, or 2. Use the default GitHub Actions token: "${{ secrets.GITHUB_TOKEN }}" Add this to your workflow file: jobs: test: runs-on: ubuntu-latest permissions: actions: read contents: read See documentation: https://docs.github.com/en/actions/security-for-github-actions/security-guides/automatic-token-authentication#permissions-for-the-github_token The token is needed to access workflow runs and artifacts from previous test executions. Without it, the action will skip previous results processing and only generate reports from the current run.
