Zerotier on Truenas core

I’m trying to install zerotier on my truenas core system. by following:

but i’m running into the error:
“repository local has no meta file, using default settings”

I’ve read in ZeroTier | TrueNAS Community
that zeroteir has been removed
But based on the guide comments it seems people are st ill able to get it working?
i’m trying to see what version of core, but i can’t find it but since it’s a recent install i’m assuming it’s the latest stable version TrueNAS CORE 13.3-RELEASE
