Begin with the linked GitHub Actions run and the stack trace, then inspect TagBot’s is_registered() path in tagbot/action/repo.py, especially _registry.get_contents(...) for Package.toml. Done means determining why GitHub returns 400 for this request and confirming the TagBot run no longer produces this report.
