I'm having the same issue with basically the same error code referencing it failing when registering the coffee_wafer item, but with just the CoffeeDelight-Fabric-1.20.1-1.4.jar and farmers-delight-fabric-1.4.3.jar (the newest 1.20.1 version for the depreciated one) and fabric-api-0.92.1+1.20.1.jar (if relevant). What fabric loader was this tested on? I'm using version 0.15.9, so I'm curious if that could be causing the issue.

Slight Update: Recompiling the mod after removing the effects from the wafers (so they work like the regular wafer), fixed the crash, so I'm guessing it has something to do with ItemDrinkWithEffectBase, although that is as far as my understanding could take me.

I have the same problem too
