[knot-dns-users] knotc conf-set - (invalid item)

Hi, For various reasons I need to write a Go wrapper around knotc conf. The problem is I am seeing weird behaviour (the below is stdout from my Go script): ######## Command being run: /usr/sbin/knotc conf-begin OK Command being run: /usr/sbin/knotc conf-set 'server.version' '299'error: (invalid item) 'server.version' = '299' Command being run: /usr/sbin/knotc conf-abortOK ######## If I take the "usr/sbin/knotc conf-set 'server.version' '299'" string generated by Go and paste it onto CLI, it returns OK ? I have tried adding "-v" flag but that does not produce any interesting output. Any idea where I might be going wrong here ? Why am I getting "error: (invalid item)" when Go executes the command, but not when I run it manually ? Thanks !
