Hi @sed-i, thanks for taking the time to report this issue. The charm was trying to patch a statefulset with a wrong name - ops.CharmMeta.name, which appears not to be the juju charm name as stated in the docs. So it was trying to patch a statefulset named oathkeeper instead of the ok alias you gave it. It will be fixed by https://github.com/canonical/oathkeeper-operator/pull/41. Thanks!
