Having the same problem but I don't want to create a Jira account nor do I know how to properly use it.

I found that the --systemd option will only work when many of the other options are omitted.

I've detailed how to use it in the context of a systemd user service in this comment, although I'm not sure how sane/approved the solution might be.
