/armoreffect does not apply effects to armor

[VimaMT]

Description of Issue

I have tried multiple types of items: leather helmets, gold helmets, iron helmets.
Command while holding item: /armoreffect NightVision
The effect is not added.
There are no error messages in the console for this.

Can confirm this is the case for me too, it worked when I was on 1.20.4. The armor pieces that had an effect working before now don't apply the effect to the player, nor can we create new armor effects.

Will be fixed with next build
