Enchanting Table Pet not opening

[Frobuzmumber]

I am using 1.9 inventory pets (1.4.6 Release) and several other mods, and when I try to open the enchanting table pet, it doesn't open. The server console shows the following error

There is no message in the client side.
I do have lapis nuggets in my inventory as well
This is a directory list with all my mods (note the .dis mods are disabled)
modlist.txt

I am using forge version 1901

This seems to ONLY happen on the server, not on single player. Config files are identical

Yep. Good catch. Had a wrong variable in there. Fixed in dev.
