After upgrade from 1.21.1 to 1.21.3, when I do gradlew runData, I get really strange error that I cannot understand:

Caused by: java.lang.NullPointerException: Item id not set

Have there been changes related on how items should be registered now?

- Modded Minecraft won't open, error code 1
  
  By Gecko1199 · Posted 50 minutes ago
  
  After looking through all of the mods and going through Forge and enabling and disabling mods the two mods that ending up being a problem were "Haybale" and "Armor and damage scaling" that would cause error code 1. As a suggestion to anyone with the same problem if you take the time to look through just enable and disable every mod, I went 10 at a time and eventually found the problem mods. Also thank you for the help it is much appreciated!
