This can happen when using fork-based workflows, such as:

  • a new forked repository is created by user A

  • user A adds new commits to this repo and creates a back-merge Pull Request to the original repository

  • user B tries to merge the Pull Request, and these commits are added to the original repository by user B

  • commits in such a Pull Request are new to the original repository and should be validated by YACC

  • YACC compares the commit author name/email with current user B - if they are different, the commit is rejected by YACC


As of YACC v2.9.0, this issue has been resolved. If you are using v2.8.4 or earlier, we recommend upgrading to the latest version. If that is not an option at this time, the suggested workaround is to use the Require Committer Matches Valid User option instead of Require Matching Committer Email / Require Matching Committer Name. It performs a less strict check for confirming the author of the commit being merged is a known Bitbucket user. See Commits on the Configuration Overview page for more information.


YACC version 1.x had a bug when all commits wrapped by Pull Requests were not validated or were skipped. This behavior is incorrect and was fixed in YACC 2.x, causing the described issue in some rare workflows.
