From 6865058f2fa9faac5ee8db6b616c0734b1bb5805 Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Mon, 10 Aug 2020 15:19:02 +0200 Subject: generate systemd: fix error handling Fix a bug in the error handling which returned nil instead of an error and ultimately lead to nil dereferences in the client. To prevent future regressions, add a test and check for the error message.
