So either the recipe or it's result is null, which IIRC is not standard behavior for this thing.
Do you have any plugins/skript that might be modifying recipes and setting the result to null instead of a stack of air?

If not though I've just loaded up and tested myself with the same Spigot version and didn't get the same exception clicking around, is there specific steps to triggering it or was it just any click?

I've removed a the skript addon wildskript which is responsible for registering the prepareitemcraftevent to skript and it has cleared the error. Although I wasn't using the event in any skripts or using wildskripts recipe functions.

It seems to be just any click on the crafting table ingredient slots that are empty. The only other plugin that is on the server that would modify recipes is australiacrafting & skquery. However once skquery is removed the exception still shows.

Any exceptions do not show once the uhc plugin is removed. Also throws an exception for each recipe changing module regardless if it is enabled or not. https://hastebin.com/dulavequka.bash
