Crash when modded villager levels up

Minecraft: 1.12.2
Forge: 14.23.5.2860
VTT: 0.6.5
Roots: 3.1.6
Contenttweaker: 4.10.0

Description:
Added and removed some trades from a modded villager (roots). The added trades include contenttweaker items. Whenever the villager updates to the level the added trade is in the game crashes with the attached crash file. I am also attaching my json file.

With some further testing (changing the trades without adding a contenttweaker item) I have inferred that the issue doesn't lie with contenttweaker but changing the recipes of a modded proffesion(?) probably
