Mixin apply failed ae2wtlib.mixins.json:PlayerInventoryInsertStack

I’m trying to create my own modpack but I can’t find the cause of this error. I’m not good with lines of code so its hard for me to diagnose anything.
Heres the error:

Sadly this is the wrong place to ask. Its not a sponge error but instead a mixin error. The error belongs to this file

ae2wtlib.mixins.json

If you know the mod from the name then great, if not my program of “Mixin Detector” (you can find on this forums site) will detect what mod uses that file.

Hopefully the mod author has a issues board or forums where you can ask on
