Thanks @Lee-W 's hint. The failure was caused by:

1. @allen91wu 's earlier commit message does not follow commitizen style, and I landed the commit. The pull request CI did not detect it because of unexpected master merge, so the commit hash was not detected correctly. We should follow commitizen commit style.
2. cz bump --yes --changelog only bump version when detecting the commit messages with fix or feat. Tip: locally place cz bump --yes --changelog --dry-run to test the version bumping.
