Unable to start oz-daemon: panic: reflect: call of reflect.Value.Int on zero Value

[onny]

Hey,
I'm trying to port oz to ArchLinux and wrote this PKGBUILD script https://aur.archlinux.org/packages/subgraph-oz/
If I run oz-daemon I get following error:

Of course my package for Archlinux is not complete yet and is missing some dependencies. But looking at this error I'm not sure how to proceed ...

Best regards,
