Trying to delete https://copr.fedoraproject.org/coprs/robert/prosody-trunk/build/154980/ via https://copr.fedoraproject.org/coprs/robert/prosody-trunk/delete_build/154980/ leads to: Error 500 : Internal Server Error 'NoneType' object has no attribute 'split' Guess this path was never tested? :-(
This also affects "Mock build from a SCM repository".
Can you please confirm that the problem still lasts? I couldn't reproduce it by neither git&tito or mockSCM. It might be connected to your specific repository then.
Issue still exists, e.g.: https://copr.fedorainfracloud.org/coprs/robert/prosody-0.9/build/154978/ https://copr.fedorainfracloud.org/coprs/robert/prosody-0.9/delete_build/154978/ https://copr.fedorainfracloud.org/coprs/robert/prosody-0.10/build/154993/ https://copr.fedorainfracloud.org/coprs/robert/prosody-0.10/delete_build/154993/ https://copr.fedorainfracloud.org/coprs/robert/prosody-trunk/build/154980/ https://copr.fedorainfracloud.org/coprs/robert/prosody-trunk/delete_build/154980/ Given this is three different repositories, I treat this as quite unlikely.
