Renovate does not recognize the last commit author

[rblin081]

How are you running Renovate?

Self-hosted Renovate

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

GitHub

Please tell us more about your question or problem

We're using Renovate to manage the dependencies in several of our GitHub repositories. We've noticed that recently there's a comment being added to the Renovate managed PRs

Renovate will not automatically rebase this PR, because it does not recognize the last commit author and assumes somebody else may have edited the PR.

Renovate is configured to use GitHub application 'honor-gh-bot' to authenticate to the different GitHub repositories

Here's the relevant GitHub action yaml

      - name: Generate GitHub app authentication token
        id: generate-app-token
        uses: actions/create-github-app-token@v1
        with:
          app-id: ${{ vars.HONOR_GH_BOT_APP_ID }}
          private-key: ${{ secrets.HONOR_GH_BOT_PRIVATE_KEY }}
          owner: ${{ github.repository_owner }}
      - name: Renovate GitHub Action
        uses: renovatebot/github-action@v40.1.12
        with:
          configurationFile: ${{ matrix.renovateConfigFilePath }}
          token: ${{ steps.generate-app-token.outputs.token }}

and here's the relevant Renovate configuration

    gitAuthor: 'Renovate Bot <bot@renovateapp.com>',
    gitIgnoredAuthors: ["honor-gh-bot"],
    platform: 'github',

    automerge: true,
    platformAutomerge: true,
    autoApprove: true,
    assigneesFromCodeOwners: true,

Note that honor-gh-bot is specifically added as an entry gitIgnoredAuthors.

Any ideas why Renovate is not recognizing the commit author?

Renovate will use platformCommit to perform signed commits via GitHub's API instead of using git directly. The git author/committer for this is determined by GitHub, using a combination of the app's name and ID.

Renovate itself can discover this email address, the logic is here:

renovate/lib/modules/platform/github/index.ts

Lines 190 to 195 in 813dd34

	if (platformConfig.isGHApp) {
	platformConfig.userDetails ??= await getAppDetails(token);
	const ghHostname = platformConfig.isGhe
	? URL.parse(platformConfig.endpoint).hostname
	: 'github.com';
	discoveredGitAuthor = `${platformConfig.userDetails.name} <${platformConfig.userDetails.id}+${platformConfig.userDetails.username}@users.noreply.${ghHostname}>`;

I recommend leaving gitAuthor blank and letting Renovate discover this. "honor-gh-bot" is also not a valid git author anyway (it must be an email).
