Leap builds - another inconsistency for python-builds

Hi, I have one package (python-pydyf) in d:l:p and in two other repos with basically the same prjconf. In one it builds, in another one its broken for 15.3, but still builds locally! In this case it fails in testing: Direct construction of IsortItem has been deprecated, please use IsortItem.from_parent. ...although pyproject.toml is patched: [tool.pytest.ini_options] addopts = '--isort --flake8 --cov --no-cov-on-fail' beside this case, I would be interested why a package build locally but sometimes on OBS, sometimes not.... Any ideas? Thanks! Axel
