Observed behaviour

Got the "java.lang.IllegalArgumentException: Can't find attribute irons_spellbooks:lightning_magic_resist", and the game crashed.
It happened when tried to cast a lightning lance spell on a mob from "Better Nether". Now the Better Nether is a fabric mod, and it only works because of a "Sinytra Connector". I know it's prob a issue of using forge and fabric mods together, but is there a way we could get a work-around?

Expected behaviour

Not crashing i think, tho not really

Steps to reproduce

In crash-log

That must mean they are not firing the forge attribute event, or that it does not include fabric mobs. We do not support the use of connector
