@gyr Have a look at https://github.com/openSUSE/sle-prjmgr-tools/actions/runs/4136962369/jobs/7151523128#step:3:33

Black appears to be not happy with the change.

Pylint too but that could be due to the osc 1.x changes and might be not related to your change. (Still would be good to fix it.)

@SchoolGuy , I've fixed black format issues.

WRT pylint ones, checking the definition of E1123, all the parameters on pylint report are valid for get_request_collection in osc/core.py. So, do you have any idea why it failed?

• So just a hint for next time: Don't use your main branch to work on anything. Merging get's hard as soon as anything is pushed to the origin main branch.
• Black is still unhappy
• pylint is unhappy because the arguments are not there in osc with version 0.182. Source for 0.182 can be seen here. Version of osc that is installed can be seen here. If you want to specify the version of osc that is used then we need to set it in setup.cfg in the install_requires. That however will be tricky as RPM packaging might work but break at runtime due to the osc version taken from the OS, instead of pip.
