A commen error when running tools/tidy in the openSUSE/SLES tests repository for openQA is the following error:
Wrong version of perltidy. Found '20211027', expected '20211029'.
This indicated a mismatch of the found vs. expected version of perltidy and the tidy script aborts to avoid inconsistent formatting between your PR and the CI pipeline. In Perl this is unfortunately necessary, as often a new version of perltidy formats the code differently. Yes, this is a source of constant struggle and one of the reasons why I dislike Perl (sorry for the mild rant).
